SCHNEIDER ELECTRIC A9L40421 - Residual Current Circuit Breaker (RCCB)
The SCHNEIDER ELECTRIC A9L40421 is a 4-pole, 40 Ampere Residual Current Circuit Breaker (RCCB) from the Acti 9 iID series, engineered for robust electrical safety. This device provides critical protection against earth leakage currents, preventing electrical shock hazards and mitigating fire risks in industrial, commercial, and residential distribution systems. It utilizes an electromechanical tripping mechanism to disconnect the circuit upon detection of a 30mA Type AC residual current, ensuring compliance with international safety standards.
