ABB 751010G0808 Drive Control Motherboard

Product Description

ABB 751010G0808 is the dedicated electronic control board for ABB VM1 medium-voltage vacuum circuit breaker with magnetic actuator. As the core control unit of VM1 magnetic actuator, it manages capacitor energy storage, controls close/open operation, collects signals from position sensors, performs circuit self-diagnosis and fault alarm output. With EMC electrical isolation and watchdog fault monitoring, it can complete switching action independent of auxiliary power supply. It is critical spare part for VM1 circuit breaker, widely used in switchgear retrofitting and equipment maintenance replacement.
