Title:
ELECTRIC LEAKAGE CIRCUIT BREAKER
Document Type and Number:
WIPO Patent Application WO/2022/135045
Kind Code:
A1
Abstract:
The present invention relates to a circuit breaker, and in particular to an electric leakage circuit breaker. The present invention uses the following technical solution: an electric leakage circuit breaker, comprising a base, a middle seat, and an upper cover, wherein the middle seat is located between the base and the upper cover; a first space is formed between the middle seat and the base, and a second space is formed between the middle seat and the upper cover; an N-pole contact device and an electric leakage tripping mechanism are provided in the first space; an L-pole contact device, an arc extinguishing chamber and a dual-metal pull rod mechanism are provided in the second space; and a movable contact seat actuation mechanism and a voltage tripper are provided above the middle seat. By means of the solution, the present invention overcomes the problem existing in the prior art, and provides a novel electric leakage circuit breaker which is rational in structure and stable in work.
