A9R12440
Schneider Electric A9R12440 Acti9 iID Residual current circuit breaker (RCCB) 4P 40A 100mA AC type. The Schneider Electric A9R12440 is a robust Acti9 iID Residual Current Circuit Breaker (RCCB) designed to provide essential earth-leakage protection in electrical installations. This 4-pole device is rated for 40A current with a 100mA AC type earth-leakage sensitivity, ensuring instantaneous detection and tripping for enhanced safety. Operating efficiently across 400-415 V AC and 50/60 Hz networks, the Schneider Electric A9R12440 is engineered for reliable performance in demanding environments. Its voltage-independent residual current tripping technology and 10 kA rated conditional short-circuit current capability make it a secure choice. Ideal for diverse industrial applications in Egypt and the Gulf, including critical infrastructure in oil and gas, water treatment plants, cement production, food and beverage processing, textiles, and large-scale building services, this RCCB is easily mounted on a 35 mm DIN rail.
