Solid State Breaker

Solid State Breaker

Solid State Breakers (SSB) are power electronic switches that are automatically operated to protect a load from damage caused by overload or short circuit. It is designed to detect a fault condition and immediately turn off thereby interrupting current flow to the load.

Unlike a circuit breaker, which mechanically operates within 10 – 100ms (depending on conditions), the SSB is designed to operate within 10 – 20μs.

Unlike a fuse, which has to be replaced, a SSB can be reset (either manually or automatically) to resume normal operation.
