A9F78220
Schneider Electric A9F78220 Miniature Circuit Breaker Acti9 iC60N 2P 20A B-Curve. The Schneider Electric A9F78220 is a robust Acti9 iC60N Miniature Circuit Breaker (MCB) designed for reliable protection in final distribution circuits. This 2-pole device features a 20A rated current and a B-curve trip characteristic, utilizing thermal-magnetic technology for effective overcurrent and short-circuit protection. It offers a breaking capacity of 6000A conforming to IEC/EN 60898-1 at 400V AC and 10kA conforming to IEC/EN 60947-2 at 380-415V AC, making it suitable for demanding electrical environments. Versatile in application, the A9F78220 supports both AC and DC networks with a 50/60 Hz frequency, accommodating operational voltages from 12V to 440V AC and up to 125V DC. Its compact design allows for clip-on mounting on a 35mm DIN rail, providing easy installation. With an IP20 degree of protection and suitability for isolation, it ensures safety and functionality in various industrial and commercial settings. Applications include critical infrastructure across the Gulf and Egypt, such as building services, water treatment plants, food and beverage processing, cement factories, and oil and gas facilities.
