Earth leakage detection circuit
WebAn RCD/RCCB in itself does not provide protection from a short circuit or other overcurrent scenario. As a result, most installations utilising RCD’s would also feature a circuit breaker in series to provide this protection. An RCBO is a single compact device which offers both earth leakage and overcurrent/short circuit protection. WebDiscover our range of products in Earth-leakage protections: VigiPacT ...
