A9F84420
Schneider Electric A9F84420 Miniature Circuit Breaker, 4P, 20A, C curve. The Schneider Electric A9F84420 is a robust 4-pole Miniature Circuit Breaker (MCB) from the Acti9 iC60 range, designed for reliable protection in final distribution circuits. Rated at 20A with a C-curve trip unit, this thermal-magnetic breaker offers essential overcurrent and short-circuit protection for both AC and DC networks. It boasts a breaking capacity of 10000A (IEC/EN 60898-1 at 400V AC) and 15KA (IEC/EN 60947-2 at 380-415V AC), ensuring high performance under fault conditions. Compatible with common operational voltages including 220-240V AC and 380-415V AC at 50/60 Hz, as well as up to 250V DC, the A9F84420 is highly versatile. Its DIN-rail clip-on mounting makes installation straightforward in industrial and commercial panels. With an IP20 degree of protection and operational temperature range from -35°C to 70°C, it is suitable for demanding environments found across Egypt and the Gulf, including applications in cement plants, oil and gas facilities, water treatment, food and beverage manufacturing, and building services. It supports wire sizes up to 25mm² rigid and 16mm² flexible.
