SCHNEIDER ELECTRIC A9R21440 - Residual Current Circuit Breaker (RCCB)
The SCHNEIDER ELECTRIC A9R21440 is a 2-pole Acti 9 iID K Residual Current Circuit Breaker engineered for robust protection against electrical shock and fire hazards resulting from earth leakage currents. This device provides instantaneous disconnection of the circuit upon detection of a 30 mA sinusoidal AC residual current, ensuring personnel safety and equipment integrity in low-voltage electrical distribution systems. It integrates into modular DIN rail assemblies for reliable earth fault protection in commercial, industrial, and residential installations.
