Solid-state

Solid-state circuit breakers (SSCBs), also known as digital circuit breakers, are a technological innovation which promises to advance circuit breaker technology out of the mechanical level, into the electrical. This promises several advantages, such as acting much more quickly (breaking circuits in fractions of microseconds), better monitoring of circuit loads and longer lifetimes. Solid-state circuit breakers have been developed for medium-voltage DC power and can use silicon carbide transistors or integrated gate-commutated thyristors (IGCTs) for switching.
