power and energy storage of electric circuit breakers
Circuit breaker
A circuit breaker is an electrical safety device designed to protect an electrical circuit from damage caused by current in excess of that which the equipment can safely carry ( overcurrent ). Its basic function is to interrupt current flow to protect equipment and to prevent fire. Unlike a fuse, which operates once and then must be replaced, a ...

Design criteria of solid‐state circuit breaker for low‐voltage microgrids
The HCBs open short-circuits in the range of milliseconds, which is significantly faster than the traditional circuit breakers. However, for low-power microgrids with small nominal operating currents, the fault clearing periods in the range of milliseconds are not acceptable [ 21, 22 ].
