Abstract

The invention relates to the field of low-voltage electric appliances, in particular to a circuit breaker. The circuit breaker comprises a circuit breaker shell, an operating button and at least two groups of circuit systems stacked in the circuit breaker shell. Each group of circuit systems comprises a circuit breaking pole circuit, and each circuit breaking pole circuit comprises an operating mechanism. The operation button is respectively in driving connection with each operation mechanism and simultaneously drives each open-circuit pole circuit to be switched on/off. The circuit breaker issmall in size and high in current-carrying capacity.

Description

technical field [0001] The invention relates to the field of low-voltage electrical appliances, in particular to a circuit breaker. Background technique [0002] With the increasing integration and miniaturization of electrical equipment, the miniaturization requirements for circuit breakers are also getting higher and higher, and there are space requirements for the wiring direction of circuit breakers. The existing circuit breakers and their terminals cannot meet the above requirements. Require. [0003] In addition, the current specifications of existing small-volume circuit breakers are too small to meet the requirements of large-current power distribution systems. Contents of the invention [0004] The object of the present invention is to overcome the defects of the prior art and provide a circuit breaker with small volume and high current carrying capacity. [0005] To achieve the above object, the present invention adopts the following technical solutions: [00...
