What is a Stored Energy Mechanism (SEM)? | Schneider
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.
