Schneider A9R44263 Acti9 iID RCCB 2P 63A 300mA Type AC

The Schneider A9R44263 is an Acti9 iID residual current circuit breaker (RCCB), rated 2P 63A 300mA Type AC, providing fire protection against earth leakage faults caused by insulation failures. The 300mA sensitivity targets fire protection in residential, commercial and industrial distribution boards, while the Type AC characteristic detects alternating sinusoidal residual currents typical of conventional resistive and inductive loads.
