A9F77420
Schneider Electric A9F77420 Miniature Circuit Breaker Acti9 iC60N 4P 20A C-Curve. The Schneider Electric A9F77420 is a robust Acti9 iC60N Miniature Circuit Breaker (MCB) designed for reliable protection in final distribution circuits. This 4-pole, 20 Amp MCB features a C-curve thermal-magnetic trip unit, ensuring effective overload and short-circuit protection for both AC and DC networks. It accommodates a wide range of operational voltages, including critical regional standards like 220-240 V AC and 380-415 V AC at 50/60 Hz, as well as up to 250 V DC. Boasting breaking capacities of 6000A Icn (IEC/EN 60898-1 at 400V AC) and 10kA Icu (IEC/EN 60947-2 at 380-415V AC), the A9F77420 guarantees high performance and safety. Its DIN rail mounting simplifies installation in industrial and commercial panels. Ideal for diverse applications across Egypt and the Gulf, including critical infrastructure in oil and gas, water treatment, cement, food and beverage, textiles, and building services, this Schneider Electric MCB ensures continuity of service and personnel safety.
