Abstract (en)
[origin: EP0386768A2] A circuit device including a leakage alarm function by incorporating in the breaker case a zero-phase current transformer for detecting a leakage current and a leakage relay for issuing leakage alarm at reception of detection signal from said zero-phase current transformer which is mounted at a remote location from main parts of the circuit breaker of the casing. Provision is also made for a particularly advantageous arrangement of indicators and switch actuating mechanism.
