SCHNEIDER ELECTRIC A9R21463 - Residual Current Circuit Breaker (RCCB)
This device is a 2-pole Residual Current Circuit Breaker from the SCHNEIDER ELECTRIC Acti 9 iID series, designed for protection against electrical shock by detecting earth leakage currents. It provides immediate disconnection of the electrical supply when a residual current exceeds its specified sensitivity, mitigating risks in industrial and commercial electrical distribution systems. This component is critical for personnel safety and equipment protection in applications requiring robust earth fault detection.
