Schneider EZ9F51363 | Miniature circuit breaker, Easy9, 3P, 63 A, C curve, 10000 A
Description
The Schneider EZ9F51363 is an Easy9 miniature circuit breaker (MCB) designed to protect low-voltage electrical circuits against overload and short-circuit currents. Featuring 3 protected poles, a 63A rated current, C tripping curve, and 10kA short-circuit breaking capacity, it is suitable for residential, commercial, and general electrical distribution applications.
The Schneider EZ9F51363 uses thermal-magnetic trip technology, combining thermal overload protection with fast magnetic protection during short-circuit conditions. Its C-curve characteristic provides a magnetic tripping range of approximately 5 to 10 times the rated current, making it suitable for circuits with moderate inrush currents.
Designed for 400V AC, 50/60Hz three-phase systems, the Schneider EZ9F51363 provides a rated short-circuit breaking capacity of 10kA at 400V AC according to IEC 60898-1. It is also suitable for electrical isolation in accordance with the same standard.
The breaker features a clear toggle operating mechanism with contact position indication, helping users and maintenance teams quickly identify the ON or OFF state of the circuit.
The Schneider EZ9F51363 uses standard clip-on DIN-rail mounting and occupies approximately 6 modules of 9mm, giving a total width of 54mm. Its compact construction makes installation straightforward inside distribution boards and modular electrical enclosures.
With a mechanical durability of up to 20,000 operating cycles, electrical durability of up to 4,000 cycles, IP20 protection, and a wide operating temperature range, the Schneider EZ9F51363 provides a practical circuit protection solution for professional low-voltage installations.
