The Eaton SNT3P18K Shunt Trip Module is a remote-trip accessory for circuit breakers, enabling fast, remote shutdown when powered by a control signal. Manufactured by Eaton, model SNT3P18K adds shunt-trip capability to a compatible breaker, allowing an electrical control input to initiate a trip without manual operation. It is used in protection schemes and safety circuits where rapid disconnection of power is required to isolate faults or meet emergency control requirements. The module provides additional trip functionality within an existing breaker setup, supporting control wiring and remote activation as part of a broader electrical safety strategy.
