Abstract

The invention discloses a miniature leakage current circuit breaker, comprising a shell divided into N pole and L pole by an intermediate substrate, the N pole is provided with an N pole contact device and an electronic leakage protection module or an electromagnetic leakage protection module; The head device is provided with N-pole contact support; the L-pole is provided with an operating mechanism, an L-pole contact device, a short-circuit release device, an arc extinguishing device and an overload release device, the operating mechanism is provided with a jumper, and the L-pole contact device is provided with There are L-pole contact bases; N-pole contact supports, L-pole contact bases and jumpers are coaxially driven through the connecting shaft. In the present invention, the N-pole contact support and the L-pole contact support are coaxially linked with the trip button of the operating mechanism, which improves the breaking capacity and product stability of the circuit breaker; the leakage protection module of the N-pole can be electronic or electromagnetic. Adopt two-in-one functional module design to reduce production cost.

Description

technical field [0001] The invention relates to the technical field of miniature circuit breakers, in particular to a miniature leakage circuit breaker. Background technique [0002] Residual Current Circuit Breaker (Residual Current Circuit Breaker) is a switch that automatically acts when the leakage current in the circuit exceeds a predetermined value. It is used to prevent personal electric shock and has the functions of overload, short circuit and leakage protection. Common current leakage circuit breakers are divided into electronic and Electromagnetic. 1P+N earth leakage circuit breaker is a small circuit breaker, including an L-pole circuit breaker and an N-pole circuit breaker. It is mainly suitable for lines with AC 50Hz / 60Hz and rated current up to 63A. [0003] The existing integral 1P+N electronic leakage circuit breaker is a combination of 1P+N circuit breaker and leakage unit, usually the L pole and N pole of the circuit breaker are arranged in a module, and ...
