CDM3 series electric operating mechanismDetailed product description：

The CDM3 series electric operating mechanism (hereinafter referred to as electric operation) is a specialized accessory for small capacity molded case circuit breakers. When combined with the circuit breaker, it can remotely electrically close, disconnect, and resend the circuit breaker to achieve centralized and automatic control of the transmission and distribution network.

characteristic
1. CDM3 has a simple electrical operation structure, small size, easy installation, no installation adjustment, and no maintenance.
2. CDM3 electric operation drives and rotates the circuit breaker through two electromagnetic magnets, resulting in low starting current.
3. CDM3 can be operated manually when there is no power supply.
4. Both AC and DC specifications are applicable (DC requires an additional rectifier power pack).
5. This device is equipped with a power automatic switching device, which quickly and automatically cuts off the power after completing an action.
