Title:
CIRCUIT BREAKER
Document Type and Number:
WIPO Patent Application WO/2023/236983
Kind Code:
A1
Abstract:
Provided is a circuit breaker. The circuit breaker comprises at least one first housing (11), and a second housing (12) assembled on one side of the first housing (11), wherein at least one circuit breaker pole (2) is provided in the first housing (11), and each circuit breaker pole (2) at least comprises a one-phase main circuit; an electric leakage protection module (3) is provided in the second housing (12), and the electric leakage protection module (3) comprises a wiring terminal and a zero-sequence mutual inductor (34); a lead-out conductive member (45) is at least connected to the one-phase main circuit; the wiring terminal is connected to a wiring sheet; a wiring port is provided on a side wall of the side of the first housing (11) that is close to the second housing (12); the lead-out conductive member (45) and/or the wiring sheet are/is connected by means of insertion through the wiring port, so as to form a plug connection structure connected to a main loop; and the lead-out conductive member (45) and/or the wiring sheet pass(es) through a wire-passage hole of the zero-sequence mutual inductor (34). The lead-out conductive member (45) of the circuit breaker pole (2) fits with the wiring sheet of the electric leakage protection module (3) to form the plug connection structure connected to the main loop, such that the circuit breaker pole (2) and the electric leakage protection module (3) which are modularized meet the requirement of the main loop for passing through the zero-sequence mutual inductor (34) during an assembling process, and the wiring is simple and convenient.
