CHALLENGER SHUNT-TRIP-AC-MCCB-RELAY-01A-SEG Shunt Trip

CHALLENGER SHUNT-TRIP-AC-MCCB-RELAY-01A-SEG is a remotely actuated shunt-trip accessory for CHALLENGER molded-case circuit breakers. When energized, it trips the breaker by activating the trip mechanism to provide rapid isolation in emergency or safety-interlock scenarios. This MCCB accessory is part of Rockwell Automation’s line of shunt-trip modules and is designed to pair with compatible MCCBs to enable remote disconnection control. Typical applications include plant safety interlocks, emergency shutdown schemes, and alarm-triggered isolation in industrial automation environments. The device is activated by a control voltage applied to the shunt-trip coil, facilitating integration with fire alarm panels, PLC safety interlocks, or building automation systems that require a hard, instantaneous disconnect. As a shunt-trip option within CHALLENGER’s MCCB portfolio, SHUNT-TRIP-AC-MCCB-RELAY-01A-SEG complements other accessories such as auxiliary contacts and motor protection modules, helping to implement a robust protection scheme for the MCCB. For exact electrical compatibility, mounting, and wiring details, refer to the official CHALLENGER literature for the 01A-SEG variant and the MCCB frame it supports, since ratings and installation requirements vary across product families.
