A9F18210

The Schneider Electric A9F18210 is a 2-pole (1P+N) Residual Current Circuit Breaker (RCCB) from the Acti 9 iID range. It is designed to provide protection against earth leakage currents (ground faults) and the risk of electric shock. It detects and trips in the event of a differential current flowing to earth, which could be caused by insulation failure or accidental contact with live parts.
