Schneider Electric A9R50425 Residual Current Circuit Breaker (RCCB) 4P 25A 30mA AC Type. The Schneider Electric A9R50425 is a robust 4-pole Residual Current Circuit Breaker (RCCB) from the Acti9 iID K series, engineered for reliable earth-leakage protection in demanding electrical installations. Designed for AC networks, this device features a rated current of 25 A and an instantaneous earth-leakage sensitivity of 30 mA, classifying it as a Type AC protector. It operates effectively within a rated operational voltage range of 380-415 V AC at 50/60 Hz, making it perfectly suited for the power grids prevalent in Egypt and the Gulf region. Its voltage-independent tripping technology ensures consistent safety, while a conditional short-circuit current rating of Inc 6 kA provides robust fault protection. Installation is simplified by its clip-on mounting mode for a 35 mm DIN rail and versatile tunnel-type terminals accommodating rigid wires up to 35 mm². This compact yet powerful RCCB is an essential component for enhancing electrical safety in critical sectors such as cement production, oil and gas facilities, water treatment plants, food and beverage processing, textile manufacturing, and various building services applications across the Middle East. For a dependable solution to protect personnel and equipment from earth-leakage faults, consider the Schneider Electric A9R50425.
