A Stored Energy Mechanism (SEM) is a mechanism that opens and closes a device (Switch) by compressing and releasing spring energy. The operating handle compresses a set of closing springs and a separate set of opening springs. These springs store the mechanical energy of this movement and are held in the compressed state by close and open latches.

While all circuit breakers perform the basic function of interrupting the flow of electricity when a fault is detected, various types of circuit breakers are designed to handle different situations. Circuit breakers work by detecting an issue in the flow of electricity, such as an excessive current or a short circuit, and automatically breaking the circuit to prevent further
