A9F74350
Schneider Electric A9F74350 Miniature circuit breaker, iC60N, 3P, 50A, C curve. The Schneider Electric A9F74350 is a robust Acti9 iC60N miniature circuit breaker, engineered for reliable protection in final distribution circuits. This 3-pole, 50A MCB features a C-curve thermal-magnetic trip unit, providing effective overload and short-circuit protection for both AC and DC networks. It supports a wide operational voltage range, including 220-240V AC and 380-415V AC at 50/60 Hz, as well as up to 180V DC. With an impressive breaking capacity of 10 kA Icu at 380-415V AC and 10 kA Icu at <= 180V DC, alongside 6000A Icn at 400V AC (IEC/EN 60898-1), the A9F74350 ensures high performance and safety. Its DIN-rail mounting makes installation straightforward, and the IP20 degree of protection (IP40 in modular enclosures) highlights its durability. This versatile circuit breaker is ideal for diverse applications across Egypt and the Gulf, including commercial buildings, industrial facilities, water treatment plants, oil and gas infrastructure, and general power distribution systems.
