Contactor-Fuse Combination 3TL62 / 63 / 66
Description General
Contactor-fuse combination 3TL62 / 63 / 66 Due to their high reliability, the contactor-fuse combinations 3TL6 are used where frequent and safe switching is required, no matter whether it is for three-phase motors, transformers, reactors, capacitors or resistive consumers. With up to one million operating cycles, the contactorfuse combinations ensure optimum availability. Their advantage: High safety and reliability due to maintenancefree systems.
The arrangement of the components on the base plate provides optimum ventilation and thus, a high normal current, supported by the especially developed fuse holder which ensures a uniform distribution of the current. Even high requirements regarding the dielectric strength – as requested in countries like China – are fulfilled with this design.

R-HG11-343.eps

The contactor-fuse combinations 3TL62/63/66 are type-tested units of the successful 3TL6 contactors and HV HRC fuses. A fuse holder for two fuses per phase and a control transformer for power supply have been integrated. This enables frequent switching of high normal currents in a compact space.
The contactor-fuse combinations 3TL6 are suitable for application on withdrawable parts and fixed-mounted assemblies. Bushings and various widths across flats are available for easy integration. There are many different versions of contactor-fuse combinations available, e.g. for one or two fuses per phase, with or without control transformer.
Contactor-Fuse Combination 3TL62 / 63 / 66
Description Construction and mode of operation
Construction

The contactor-fuse combination consists of the following components: vacuum contactor (1), insulating cover with fuse holder (2), fuse-links (3), isolating contacts (4), and an optional control transformer (5). These components are accommodated on a base plate (6).

The vacuum contactor (1) breaks the relevant currents during normal operation. To do this, the vacuum switching technology, proven for more than 30 years, serves as arc-quenching principle by using vacuum interrupters. The vacuum interrupters (8) are operated by the magnet system (10) through an integral rocker (9). All components required for switching, such as the operating mechanism and closing latch (11) are accommodated in the operating mechanism box (12) and are fed with low voltage. This low voltage is either supplied separately or taken directly from the mediumvoltage system through the optional control transformer (5).

The isolating contacts (4) enable the connection to the medium-voltage system. For fixed mounting there are flat contacts available, and plug-in contacts for integration in withdrawable systems. With this type, the ring spring contact version offers an especially large contact surface and optimum power connection. The circumferential ring spring expands when the fixed contact is pushed in, providing a large contact surface. To insulate the contact arms, a plastic insulating sleeve is used, which can be adjusted to the different lengths of the contact system. A width across flats of 205, 275 or 310 mm is reached by different adjustments to the cross-members or the insulating covers with fuse holders. The optional control transformer (5) is connected to the high-voltage terminals of the contactor-fuse combination on its primary part, so that no additional cables are required. To protect the transformer, an separate upstream fuse is series-connected on the primary side and accommodated in the cross-member. Due to its different versions, the control transformer can be optimally adjusted to the existing power system. The front cover (13) closes the insulating cover with fuse holder with an indication opening, and offers a possibility for handling.

The fuse-links (3) from different manufacturers can be used. Here, a maximum let-through current of 50 kA must be observed in order not to damage the contactor. To select the correct fuse-link, please observe the indications given in the chapter “Equipment Selection” (see page 16).
HG11-2737a eps
The insulating cover with fuse holder (2) is mounted on one side of the contactor (1). On the other side it is raised to the necessary height by the cross-member (7). The fuse holders, which are especially conceived for the use of up to two plugin HV HRC fuse-links, ensure a uniform distribution of the current to the two fuse-links of one phase.

Basically, there are three different modes or states of operation: Normal operation, short circuit and overload. During normal operation, the combination behaves like a contactor. The atmospheric pressure exerts a force on the metal bellows of the vacuum interrupter. Without the influence of the operating mechanism, this would close the contact gap. HG11-2739a eps

The opening springs (1) keep the moving interrupter contact in open position via the integral rocker (2). To close the vacuum contactor, the compressive force of the opening springs (1) is overcome by the magnet system (3). The DC magnet system operates as an economy circuit, providing a high mechanical endurance and a low pickup and holding power. The magnet armature (4) is attracted, thus moving the integral rocker (2), which releases the moving interrupter contact from the open position. The atmospheric pressure closes the contacts. The integral rocker (2) compresses the contact pressure springs (5), thus generating the necessary contact force. When the magnetic excitation is de-energized, the opening springs (1) open the contact gap via the integral rocker (2) and the moving interrupter contact. When a mechanical closing latch is used, the adjustment is maintained through a latch lever even if the magnet coil is not excited. The vacuum contactor is released electrically by means of a latch release coil, or mechanically by means of a latch release device. In case of overload, a high continuous current overloads the fuse-link thermally, thus tripping the thermal striker (11). The contactor already operates within the arcing time of the fuse. The take-over current must not exceed 5 kA, as this could damage the vacuum interrupter! This is prevented by selecting the correct fuse. In case of short circuit, the main fuse-elements (10) of the HV HRC fuse melt and evaporate at all bottlenecks already during the current rise. Arcs burn at these bottlenecks, which are cooled so effectively by the arc-quenching medium that their total arc voltage is higher than the operating voltage. This results in a rapid decrease of the current, which is interrupted while it is still rising. When the main fuse-elements (10) melt, the secondary fuse-element (8) evaporates as well and releases the thermal striker (11), which operates the vacuum contactor with the help of the auxiliary switch and activates the fuse trip indicator. In the optimum time sequence, the fuse has already interrupted the short-circuit current at this time.

Description Construction and mode of operation
Replacement of HV HRC fuses The fault currents stress the fuses in the phases differently, but all fuses are stressed. To obtain identical switching and safety conditions for further application again, all fuse-links should be replaced as recommended in the standards.
Scope of delivery
We advise to use our Siemens 3GD2 HV HRC fuse-link for our contactor-fuse combination. For more Information see Catalog HG 12.31, Order No. E50001-K1512-A311-A2-7600 (available as of 2011).

Optional: 2 fuses per phase parallel
Short-circuit protection of HV HRC fuses At high short-circuit currents, HV HRC fuses have a currentlimiting effect, i.e. the fuse limits the short-circuit current to the let-through current. To select the fuses, the type of consumer must be observed, e.g. motor, transformer, capacitors.

An example for the coordination of contactor and HV HRC fuses is given in the chapter “Equipment Selection”. Application examples Contactor-fuse combinations are suitable for operational switching of alternating-current consumers in indoor switchgear, and can be used e.g. for the following switching duties: • • • • • • •
Starting of motors Plugging or reversing the direction of rotation of motors Switching of transformers Switching of reactors Switching of resistive consumers (e.g. electrical furnaces) Switching of capacitors Switching of compressors.
With these duties, contactor-fuse combinations are used in conveyor and elevator systems, pumping stations, air conditioning systems as well as in systems for reactive power compensation, and can therefore be found in almost every industrial sector. Utilization categories In IEC 60470, medium-voltage power contactors are divided into different utilization categories. According to these categories, contactor-fuse combinations 3TL62/63/66 are dimensioned for different electrical consumers and operating conditions. The opposite table shows typical applications in accordance with the respective utilization categories.

Reactors
Contactor-fuse combinations 3TL62/63/66 are especially suitable for frequent operation of motors in utilization category AC-3 and AC-4. As the chopping currents of the contactors are ≤ 5 A, no unpermissibly high overvoltages are produced when started motors are switched during normal operation. However, when high-voltage motors with starting currents of ≤ 600 A are stopped during start-up, switching overvoltages may arise. The magnitude of these overvoltages can be reduced to harmless values by means of special surge limiters. Switching of transformers

Overvoltages can arise as a consequence of multiple restrikes or by virtual current chopping, e.g. when motors are switched in braked condition or during start-up. Motors with a starting current ≤ 600 A are endangered. Safe protection against overvoltages is ensured by surge limiters; circuit examples are shown on the left. 3EF surge limiters can be arranged in parallel to the cable sealing ends, preferably in the cable compartment. The surge limiters consist of non-linear resistors (metal-oxide varistors SIOV) and a series-connected spark gap. During installation it must be observed that the surge limiter is flexibly mounted on one side for mechanical reasons.

Contactor-Fuse Combination 3TL62 / 63 / 66
Equipment Selection Selection aids
Selection aids The contactor-fuse combination is selected in two steps: 1) The basic device is selected in accordance with the requirements of the medium-voltage system and the switching duty. 2) Selection of a suitable fuse. Generally, fuses of any manufacturer can be used, if they fulfil the standard IEC 60282-1, IEC 60644 and IEC 60787. The selected fuse must contain a thermal striker of the “medium” type.
2
The HV HRC fuse used breaks this damped short-circuit current safely. Its minimum breaking current must therefore be lower than the fault current to be expected. Discrimination requirements between HV HRC fuses In individual cases, e.g. in line systems with widely separated substations, the discrimination of series-connected HV HRC fuses may be important for operational reasons. The superior HV HRC fuse must have a higher pre-arcing I2t-value as the operating I2t-value of the subordinate fuse. Discrimination requirements between HV HRC and LV HRC fuses
But we advise to use our Siemens 3GD2 HV HRC fuse-link for our contactor-fuse combination. For more Information see Catalog HG 12.31, Order No. E50001-K1512-A311-A2-7600 (available as of 2011).
When the associated LV HRC fuse is selected, discrimination to the HV HRC fuse must be ensured. This equally applies if the low-voltage feeder contains several parallel fuses.
Transformer protection
In the case of LV HRC fuses with different current ratings, the fuse with the maximum current rating is decisive for discrimination considerations.
HV HRC fuses as short-circuit protection for transformers DIN VDE 0670 Part 402 achieved a standardization of the HV HRC fuse characteristics – referring to their rated current. This results in a protection recommendation for distribution transformers which is widely independent of the fuse manufacturer. A minimum or maximum fuse current rating is assigned to each transformer. This larger range provides improved discrimination coordination both towards the low-voltage side and the superior medium-voltage side.
Discrimination requirements between HV HRC fuses and low-voltage circuit-breakers Discrimination must be ensured by means of the time-current characteristics of the HV HRC fuse-link converted to the low-voltage level and the total breaking time of the provided circuit-breaker. Motor protection HV HRC fuses as short-circuit protection of motors
Moreover, there are further requirements for special applications, which are described in the relevant standards.
HV HRC fuses are used for short-circuit protection in combination with vacuum contactors.
Inrush current
Due to the arising motor starting current, the instant when the motor starts represents the maximum stress for the HV HRC fuse. This stress must neither operate nor pre-damage the fuse. Other factors of influence on the stress of the HV HRC fuses are the starting time and the starting frequency.
For the specified ratings of distribution transformers, the effects of inrush currents (I2t-values) on the upstream HV HRC fuses have been checked. The most important factors of influence are the rated power, vector groups and impedance voltages of the transformers. According to IEC 60787, Clause 4, the pre-arcing time characteristic of the fuse at a time of 0.1 s must feature a current value greater than 10 to 12 times the rated transformer current. Short-circuit protection on the low-voltage side of the transformer When there is a short-circuit on the low-voltage side at the transformer terminals, a damped short-circuit current flows on the high-voltage side: Ik = IrT y 100 Uk Ik Sustained symmetrical short-circuit current IrT Rated current of the transformer Uk Relative impedance voltage (%)
16
Siemens HG 11.22 · 2010
The indications of the fuse manufacturer regarding motor protection must be generally observed. As a guide value for 2 to 6 starts per hour (max. 2 shortly after each other), the pre-arcing current of a fuse to be selected must be at least twice the motor starting current for the given starting time. For a higher number of starts, a fuse of the next higher level must be selected.

Coordination of the components of the motor circuit: • The time-current characteristic must be located on the right of the motor starting current (point A). • The rated current of the HV HRC fuse-link must exceed the normal current of the motor. • The current corresponding to the intersection B of the HV HRC fuse-link characteristic and the characteristic of the overcurrent-time protection must be higher than the minimum breaking current of the HV HRC fuse-link. If this is not feasible, it must be ensured that overload currents that are smaller than the minimum breaking current of the HV HRC fuse-link are interrupted by the vacuum contactor via the striker. This prevents thermal overloading of the HV HRC fuse-link, which would otherwise be destroyed. • The rated breaking current of the vacuum contactor must be higher than the minimum breaking current of the HV HRC fuse-link, and higher than the current resulting from the intersection B of the HV HRC fuse-link and the overcurrent-time protection characteristics. • The maximum let-through current ID of the contactor-fusecombination shall be limited trough the HV HRC fuse-links (one or two in parallel). • The integral of the square of the current over a given time interval (I2t-value) is a measure for the thermal short-time stress of the elements of a circuit. The pre-arcing I2t-value of the fuse to be selected must not exceed the maximum permissible I2t-value of the contactor-fuse combination. • The thermal power loss of the HV HRC fuse-links shall not exceed the maximum value of the contactor-fuse-combination. With integrating the CFC into a panel a reduction though decreased ventilation has to be taken into account. • The contactor-fuse combination 3TL6 is optimized regarding current integral and power losses for using Siemens HV HRC fuse-links 3GD2 in accordance with the selection on page 13.

The low-voltage part covers the auxiliary devices which are necessary for operating and controlling the contactor-fuse combination. Fuselinks must be selected separately.
In case of special versions, “- Z” is added to the order number and a descriptive order code follows. If several special versions are required, the suffix “- Z” is listed only once. If a requested special version is not in the catalog and can therefore not be ordered via order code, it has to be identified with Y 9 9 after consultation. The agreement hereto is made between your responsible sales partner and the order processing department at the Switchgear Factory in Berlin.
Order codes Individual equipment versions are explained more in detail by an order code. Several order codes can be added to the order number in succession and in any sequence.

Configuration example In order to simplify the selection of the correct order number for the requested contactor-fuse combination, you will find a configuration example on each page of the chapter “Equipment Selection”. For the selection of auxiliary voltages, additional components, width across flats, etc. the last example of the primary part is taken over and continued, so that at the end of the equipment selection (page 23) a completely configured contactorfuse combination results as an example.
