The iC65HI is a high breaking capacity miniature circuit breaker with short-circuit protection, overload protection, isolation function, and fault trip indication. It is suitable for circuit protection in industrial, commercial, and power distribution systems.
The iC65HI circuit breaker is a high breaking capacity miniature circuit breaker designed in accordance with GB/T 14048.2 and IEC/EN 60947-2 standards. It is suitable for AC 50/60Hz power distribution systems.
The product 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.
This series is available in 1P, 2P, 3P, and 4P configurations, with rated currents from 1A to 63A. Depending on voltage and current specifications, the breaking capacity can reach up to 70kA. The product can be mounted on a 35mm standard DIN rail, with flexible installation direction, making it suitable for residential, commercial, industrial distribution cabinets, and terminal distribution systems.
