Problems solved by technology

However, under many abnormal conditions, such as when there is a large electric shock wave impact current, its interruption system will lose the ability to trip, and the reset button will fail, but it can still be pressed, and it will not function as a tripping protection, resulting in destruction

Abstract

An earth fault circuit breaker with a reset lock and a protection device suits different appliances, instruments, devices, equipments and systems using power characterizing in mounting the lock device on the reset button or a reverse trip protection device. A conductive static contactor is fixed on a load connection piece and directly contacts with the conductive moving contactor of the input end. This invented reset button of the breaker is more protective and more reliable compared with technologies before.

Description

technical field [0001] The invention relates to a ground fault circuit breaker, in particular to a ground fault circuit breaker with a reset lock protection device. Widely used in various electrical appliances, instruments, devices, equipment and systems that use power. Background technique [0002] Electrical appliances, instruments, devices, equipment, and systems that use power supply have power input terminals that can be connected to the power supply and load terminals that can be connected to one or more loads. There is at least one path of an inductive circuit between both the input terminal and the load terminal. If the power input terminal is mistakenly used as the load terminal, or the load terminal is mistakenly used as the power input terminal, or if the grounding fails, it will cause damage to the above-mentioned electrical equipment, and even cause a fire, endangering personal safety. Therefore, it is very important to be able to disconnect the circuit immedi...
