A9F75450
Schneider Electric A9F75450 Miniature Circuit Breaker Acti9 iC60N 4P 50A D-Curve. The Schneider Electric A9F75450 Acti9 iC60N Miniature Circuit Breaker offers robust thermal-magnetic protection for final distribution circuits. This 4-pole, 50A device features a D-curve tripping characteristic, making it ideal for loads with high inrush currents such as motors, transformers, and discharge lighting systems. It ensures reliable circuit protection with a 6000A breaking capacity (Icn at 400V AC per EN/IEC 60898-1) and a 10kA breaking capacity (Icu at 380-415V AC per EN/IEC 60947-2, also 10kA Icu at <=250V DC). Designed for versatility, the A9F75450 supports both AC (50/60 Hz across various voltages up to 440V) and DC networks (up to 250V). Its compact 35mm DIN rail mountable design (85mm H x 72mm W x 78.5mm D) simplifies installation in industrial and commercial panels. With an IP20 rating (IP40 in a modular enclosure) and an operational temperature range of -35 to 70 °C, it's built for demanding environments. This MCB is perfectly suited for critical applications across Egypt and the Gulf, including building services, water treatment plants, oil and gas facilities, food and beverage manufacturing, and textile industries.
