A9F79440
Schneider Electric A9F79440 Miniature circuit breaker (MCB), Acti9 iC60N, 4P, 40A, C curve. The Schneider Electric A9F79440 is a robust, 4-pole miniature circuit breaker (MCB) from the Acti9 iC60N series, engineered for reliable protection of final distribution circuits. Rated at 40 A with a C-curve trip characteristic, this thermal-magnetic MCB ensures effective overload and short-circuit protection for both AC and DC networks. It offers significant breaking capacities of 6000 A conforming to IEC/EN 60898-1 (at 400 V AC) and 10 kA conforming to IEC/EN 60947-2 (at 380-415 V AC or <= 250 V DC). Designed for 35 mm DIN rail mounting, its IP20 degree of protection (IP40 in a modular enclosure) makes it suitable for various environments. This versatile Schneider Electric MCB is ideal for critical distribution circuits in industrial settings like cement plants, oil and gas facilities, water treatment plants, food and beverage manufacturing, and textile factories, as well as commercial building services across Egypt and the Gulf.
