Abstract
A solid-state trip device including an instantaneous trip device formed by arc detectors 46R, 44S, 46T located in proximity to the main contacts 17R, 17S, 17T of the circuit breaker 10. The light signals emitted by the arc detectors 46R, 46S, 46T are transmitted by optical fibers 48 to a light-sensitive electronic component which emits an arcing signal. This arcing signal causes tripping of the circuit breaker 10 only if a fault signal is present.
