The Electroswitch Series 24 Three-Phase TCM, Trip Coil Monitor, provides continuous monitoring of each phase of a Breaker Trip Coil. The TCM is a convenient panel-mounted relay that provides continuous monitoring of trip coils, and 52B auxiliary contacts utilizing 3 bi-color LEDs for visual indication of trip coil and breaker position status for each phase. The Series 24 TCM monitors the individual phases from each trip coil power supply, thereby meeting the Northeast Power Coordinating Council’s requirements for the monitoring of a single-pole tripping to ensure proper breaker operation should there be a single trip coil failure.
