A small circuit breaker typically has a manual control lever to switch the circuit off or reset a tripped breaker, while a larger unit may use a solenoid to trip the mechanism, and an electric motor to restore energy to springs (which rapidly separate contacts when the breaker is tripped).
A solid-state DC breaker switch is able to interrupt the full short-circuit current in microseconds. With such a time constraint, an autonomous switch control system must ensure local fault protection, without the need for external control or fault detection.
SEL, AREVA, and ABB Group's were early forerunners making some of the early market advances in the arena, but the arena has become crowded today with many manufacturers. In transmission line and generator protection, by the mid-1990s the digital relay had nearly replaced the solid state and electro-mechanical relay in new construction.
On Monday, Ideal Power Inc (NASDAQ:IPWR) announced that it had secured its first design win for solid-state circuit breakers (SSCBs) with one of the largest circuit protection equipment ...
A solid state relay (SSR) is an electronic switching device that switches on or off when an external voltage (AC or DC) is applied across its control terminals. They serve the same function as an electromechanical relay , but solid-state electronics contain no moving parts and have a longer operational lifetime.
