A9F74450
Schneider Electric A9F74450 Miniature Circuit Breaker (MCB) 4P 50A C-Curve. The Schneider Electric A9F74450 Acti9 iC60N is a robust Miniature Circuit Breaker (MCB) designed for reliable protection in final distribution circuits. This 4-pole device features a 50A rated current and a C tripping curve, making it ideal for a wide range of electrical installations. It offers versatile compatibility with both AC (from 12V up to 440V, 50/60 Hz) and DC (up to 250V) networks, ensuring broad application flexibility. Key breaking capacities include 10 kA Icu at 380-415 V AC (EN/IEC 60947-2) and 6000 A Icn at 400 V AC (EN/IEC 60898-1). Designed for easy installation, it mounts on a 35 mm DIN rail and operates reliably in ambient temperatures from -35 to 70 °C, with IP20 protection (IP40 in an enclosure). The Schneider Electric A9F74450 MCB is a critical component for ensuring safety and operational continuity in diverse applications across Egypt and the Gulf, including building services, water treatment plants, oil and gas facilities, food and beverage processing, and general industrial distribution.
