Circuit breaker is definitely a kind of important circuit device.A circuit breaker is a switching device capable of turning off, carrying and breaking current under normal circuit conditions, and can turn off, carrying and breaking current under abnormal circuit conditions (including short circuit conditions) for a specified period of time. Circuit breaker A switching device capable of turning on, carrying and breaking current under normal circuit conditions and of turning on, carrying and breaking current under abnormal circuit conditions for a specified period of time. The circuit breaker is generally composed of a contact system, an arc extinguishing system, an operating mechanism, a release device, and a housing. When the short circuit, the magnetic field generated by the large current overcomes the reaction spring, the release device pulls the operating mechanism to act, and the switch is tripped instantaneously. When the overload, the current becomes larger, the heat is intensified, the bimetal sheet deformation to a certain extent to promote the mechanism action, the greater the current, the shorter the action time. Circuit breakers are widely used in power systems, building electrical systems, industrial equipment and various circuits to provide circuit protection and safety. They exist in a variety of types and specifications to meet the needs of different applications.
