Motor drive MCH ACB1 400V AC SE SPA-MCH164A Systeme Electric

MCH motor reducer accumulates energy to close the SystemePact ACB1 circuit breaker when it is energized and the circuit breaker is open. The motor reducer closes the circuit breaker upon receiving a command to the XF closing coil. When voltage in the motor reducer control circuit disappears, the closing spring can be manually charged using the spring charging lever (formerly Schneider Electric MASTERPACT ACC 33179).
