An electrical circuit breaker is a switch device that can be operated automatically or manually to control and protect the power system, as well as the electronic devices connected to it. When too much current flows or cannot cope with excessive current load, the circuit breaker will trip. ...
A circuit breaker includes a trigger assembly having first and second trigger members, and a tripping mechanism configured and disposed to act upon the first and second trigger members to selectively open an electrical circuit upon receipt of a mechanical trip signal input, and provide a mechanical...

An arc-fault circuit interrupter (AFCI) or arc-fault detection device (AFDD) is circuit breaker designed to detect electrical arcs that could cause a fire. Loose wire connections can cause electrical arcing and ultimately enough heat to start a fire. In the US these circuit breakers have been...
摘要：The invention relates to a tripping unit (1) for tripping the main contacts (23a, 23b, 23c) of main circuits (3a, 3b, 3c) of a circuit breaker (2) by sending an electrical tripping-signal to a switching unit (22) of the circuit breaker (2) when a current above a certain ...
If your electrical system suffers from frequent circuit breaker trips, it could be a sign of a more serious problem. Frequent trips could be a sign of a problem with yourhome’s wiringor could be evidence of an inadequate circuit in need of an upgrade. Mister Sparky® is ready to send...
