SCHNEIDER ELECTRIC A9R26440 - Residual Current Circuit Breaker (RCCB)
This device is a modular residual current circuit breaker from the Acti 9 iID series, engineered for robust protection against electrical shock by indirect contact and fire hazards resulting from insulation faults. It continuously monitors for earth leakage currents in AC electrical installations, providing rapid disconnection when a preset residual current threshold is exceeded. This component is suitable for integration into industrial and commercial distribution boards requiring precise fault current detection and enhanced personnel safety.
