A9F77450
Schneider Electric A9F77450 Miniature Circuit Breaker iC60N 4P 50A C Curve. The Schneider Electric A9F77450 miniature circuit breaker is a robust and essential component for ensuring electrical safety and reliability in diverse industrial and commercial applications. As part of the highly regarded Acti9 iC60N range, this 4-pole, 50A, C-curve MCB is engineered for efficient protection against overcurrents and short-circuits in final distribution circuits. It supports both AC and DC network types, operating seamlessly across 50/60 Hz frequencies, and offers impressive breaking capacities of 10kA (IEC/EN 60947-2) at 380-415 V AC and 6000A (IEC/EN 60898-1) at 400 V AC. Designed for easy installation on a 35 mm DIN rail, the Schneider Electric A9F77450 features thermal-magnetic trip technology for reliable performance. Its suitability for isolation, wide operational temperature range of -35…70 °C, and IP20 (IP40 in enclosure) rating make it ideal for demanding environments. This versatile MCB is a cornerstone for electrical installations in critical sectors across Egypt and the Gulf, including cement production, oil and gas facilities, water treatment plants, food and beverage manufacturing, textiles, and general building services.
