POSTED BY Protec Tech Team

The protective devices that are used for the oversight and operational decision making in low voltage circuit breakers (LVCBs) are are often simply referred to as a Solid-State Trip device (SST).  They are essentially protective relays that are frequently an integrated part of a low voltage circuit breaker and monitor the primary current path of the circuit breaker.  In normal operation, these solid-state trip devices will sense changes in the primary current path and make the decision to open the circuit based on the magnitude and duration of the fluctuation.
