The invention discloses a circuit breaker which is easy to carry and install spare parts to prevent overload damage. It includes a body, a back cover, a gear and a screw rod. Inside, the end of the rear cover is fixed with a protective plate, a protective sheet is placed in the telescopic slot, a dial is fixed on the outside of the protective sheet, and a first movable shaft is connected to the front edge of the body. A rod, one side of the body is provided with a storage slot, a docking rod is placed in the storage slot, and a second movable rod is connected to the edge of the front side of the device body away from the axis of the first movable rod. The circuit breaker is easy to carry and install spare parts to prevent overload damage. In the absence of tools, the circuit breaker can be quickly disassembled and installed, which is convenient for replacing internal damaged parts. At the same time, it is convenient for combined installation of multiple circuit breakers. Facilitates quick disassembly of individual circuit breakers in tight spaces.
Description
technical field [0001] The invention relates to the technical field of circuit breakers, in particular to a circuit breaker which is easy to carry and install spare parts to prevent overload damage. Background technique [0002] The circuit breaker is a switching device in the circuit system, which can close, carry and break the current under normal circuit conditions. It is internally composed of contact system, arc extinguishing system, operating mechanism, release and other components; [0003] Circuit breakers can be divided into high-voltage circuit breakers and low-voltage circuit breakers according to their scope of use. In the use of low-voltage circuit breakers, molded case circuit breakers are usually used for switching operations. They are small in size, easy to carry, and widely used. However, existing The molded case circuit breaker has the following problems in use; [0004] In the use of circuit breakers, especially molded case circuit breakers, the installat...
