Product Description

Medium Voltage V-Contact VSC Contactors

The medium voltage V-Contact VSC contactors are apparatus suitable for operating in alternating current and are normally used to control users requiring a high number of hourly operations. The V-Contact VSC contactor introduces the drive with permanent magnets, already widely used, experimented and appreciated in medium voltage circuit-breakers, into the worldwide panorama of medium voltage contactors.

The experience acquired in the field of medium voltage circuit-breakers fitted with drives with "MABS" permanent magnets has made it possible to develop an optimised version of the actuator (bistable MAC drive) for medium voltage contactors. The drive with permanent magnets is activated by means of an electronic multi-voltage feeder. Three bands of power supply are available with which all the voltage values required by the major international Standards can be covered.

Available Versions:

SCO (Single Command Operated): Closing takes place by supplying auxiliary power to the special input of the multi-voltage feeder. Opening takes place when the auxiliary power is cut off.

DCO (Double Command Operated): Closing takes place by supplying the input of the closing command in an impulsive way. Opening takes place when the input of the opening command is supplied in an impulsive way.

Frequently Asked Questions

1. What are the advantages of V-Contact VSC contactors?
They utilize permanent magnet drive technology, which is highly reliable, energy-efficient, and suitable for applications requiring a high number of hourly operations.
2. What is the difference between SCO and DCO versions?
SCO (Single Command Operated) opens when auxiliary power is lost or cut off. DCO (Double Command Operated) requires an impulsive input signal for both opening and closing operations.
3. What products are included in your electrical distribution line?
We offer a full range including circuit breakers, contactors, relays, isolators, surge protectors, fuses, and general switching power supplies.
