Abstract

A leakage circuit breaker, comprising: an incoming line terminal, a circuit breaker assembly, a leakage protection assembly, and an outgoing line terminal arranged in sequence along a first direction, wherein the leakage protection assembly includes: a zero-sequence transformer configured to sense leakage current to output a sensing signal; a control circuit, disposed on an electronic circuit board, configured to receive the sensing signal and determine whether the leakage current exceeds a threshold based on the sensing signal; and an action actuator, configured to It is configured to perform an action when the leakage current exceeds the threshold, so that the circuit breaker assembly disconnects the circuit, wherein the zero sequence transformer and the action actuator are arranged on the second of the electronic circuit board direction, the second direction is orthogonal to the first direction.

Description

technical field [0001] The present disclosure relates generally to earth leakage circuit breakers, and in particular to an integrated earth leakage circuit breaker. Background technique [0002] When the leakage current in the circuit exceeds a predetermined value, the leakage circuit breaker quickly performs an action to break the circuit. Generally, an earth leakage circuit breaker is an assembled type, which includes a circuit breaker module and an earth leakage product module assembled together side by side. Such an earth leakage circuit breaker takes up a lot of space, and requires manual wiring, which is time-consuming and labor-intensive. Contents of the invention [0003] An embodiment of the present disclosure provides an earth leakage circuit breaker that integrates an earth leakage product module and a circuit breaker module while ensuring the performance of the earth leakage circuit breaker to realize an integrated earth leakage circuit breaker, thereby not on...
