Each ISM comes complete with an electronic control module (CM-1501) which provides trip and close functionality. The control modules work with multiple auxiliary voltages, from 24VDC to 220VAC. The CM-1501 utilizes a patented intelligent control principle that reduces closing times and simultaneously increases the mechanical life of the circuit breaker. The lightweight aluminum housing and compact design make them easy to fit into any low voltage switchgear compartment or directly onto retrofit draw-out trucks.

The CM-1501 series eliminates the need for close and trip coils. Dry contacts are used instead, feeding into the close and trip inputs of the modules. Multiple contacts can be wired in parallel for extended remote operations.

The control module continuously monitors the health of both the breaker and the control module itself, providing status indication through LED’s mounted on the front and through external signaling relays for remote indication. The close command will be blocked in the event of a failure or loss of communication with either the breaker position switch or the magnetic actuator, only allowing the breaker to be tripped until the fault is rectified. Anti-pumping duty is built into the control logic.
