Abstract

An electric leakage circuit breaker comprises an line entry terminal, a circuit breaker assembly, an electric leakage protection assembly and a line exit terminal that are sequentially disposed in a first direction. The electric leakage protection assembly comprises: a zero-sequence transformer, configured to detect an electric leakage current in a sensing circuit to output a sensing signal; a control circuit, disposed on an electronic circuit board, and configured to receive the sensing signal and determine whether the electric leakage current exceeds a threshold according to the sensing signal; and an action execution mechanism, configured to execute an action when the electric leakage current exceeds the threshold, so that the circuit breaker assembly cuts off the circuit. The zero-sequence transformer and the action execution mechanism are disposed on a first side in a second direction of the electronic circuit board, and the second direction is orthogonal to the first direction.
