A9F74440
Schneider Electric A9F74440 Acti9 iC60N Miniature Circuit Breaker 4P 40A C-Curve. The Schneider Electric A9F74440 Acti9 iC60N Miniature Circuit Breaker (MCB) is a robust and essential component for safeguarding final distribution circuits against overcurrents and short-circuits. Designed for DIN rail mounting, this 4-pole, 40A, C-curve thermal-magnetic breaker offers reliable protection for both AC and DC networks. It boasts a breaking capacity of 6000 A Icn at 400 V AC conforming to EN/IEC 60898-1 and 10 KA Icu at 380-415 V AC conforming to EN/IEC 60947-2, making it perfectly suited for the electrical standards prevalent across Egypt and the Gulf region. With an IP20 rating (IP40 in a modular enclosure) and a wide operating temperature range from -35 to 70 °C, the A9F74440 ensures stable performance in diverse environmental conditions. Its suitability for isolation, coupled with precise thermal-magnetic tripping technology, guarantees safety and operational integrity. This versatile Schneider Electric MCB is widely used in critical applications such as building services, HVAC systems, and general power distribution within industries like cement, oil and gas, water treatment, food and beverage, and textiles.
