Schneider Electric A9F78425 Miniature Circuit Breaker (MCB) Acti9 iC60N 4P 25A B-curve. The Schneider Electric A9F78425 is a robust Acti9 iC60N Miniature Circuit Breaker (MCB) engineered for reliable electrical protection in final distribution circuits. This 4-pole, 25A MCB features a B-curve trip characteristic, making it suitable for general purpose protection where inrush currents are not excessively high. Designed for both AC and DC networks operating at 50/60 Hz, it offers significant versatility for diverse electrical systems. Key specifications include a rated breaking capacity of 6000 A (IEC/EN 60898-1) at 400 V AC and 10 kA (IEC/EN 60947-2) at 380-415 V AC, ensuring robust fault protection. Its thermal-magnetic trip unit technology provides effective overload and short-circuit protection. With DIN-rail mounting and an IP20 degree of protection, this MCB is ideal for a wide array of applications across Egypt and the Gulf region. It is perfectly suited for electrical infrastructure in building services, water treatment plants, food and beverage facilities, and general industrial distribution panels within industries like cement and textiles. The A9F78425 also boasts suitability for isolation, enhancing safety.
