FAQ

Q: Can this board be used with other ABB vacuum contactors?
A: It is specifically designed for V-Contact VSC series medium-voltage contactors. Compatibility with other series is not guaranteed.

Q: What precautions are required during replacement?
A: Always discharge the storage capacitors before handling, as they may retain high-energy charges even after power is disconnected.

Q: How does the bistable actuator control work?
A: The board powers the actuator only during transitions. Permanent magnets maintain the contactor state without continuous energy use, reducing power consumption.
