motor mechanism MCH 100 to 125 V DC

This is a motor mechanism (MCH) for MasterPact NW circuit breakers. The motor mechanism module is used to remotely open and close the circuit breaker electrically. It is made up of a spring-charging motor equipped with an opening release and a closing voltage release. The spring-mechanism charging handle is used only as a backup if auxiliary power is absent. It is equipped with a 10A limit switch contact (CH) that signals the charged position of the mechanism. The operational control voltage is 100/130VDC. The operating threshold is between 0.85xUn and 1.1xUn. The charging time is less than 4s. The maximum operating frequency should not exceed 3 cycles per minute.
