Model: ich5m
Series: ic65m
Product category: Circuit Breaker

Product overview

The iC65M circuit breaker belongs to the Acti9 Pro series of miniature circuit breakers and is available with B, C, and D trip curves to meet the protection requirements of different types of loads. The product complies with GB/T 14048.2, IEC/EN 60947-2, and UL 1077 standards, and is suitable for AC 50/60Hz power distribution systems. It provides short-circuit protection, overload protection, and isolation function, with clear indication of fault disconnection. The front viewing window displays a red indication when the circuit breaker trips due to a fault, helping maintenance personnel quickly identify the device status on site. The iC65M is available in 1P, 2P, 3P, and 4P configurations, with rated currents from 1A to 63A. Depending on voltage, pole configuration, and rated current, the breaking capacity can reach up to 100kA. The product is suitable for standard distribution boxes and terminal distribution systems, including residential buildings, commercial buildings, industrial control cabinets, and power distribution equipment.
