Schneider Electric Acti9 Pro iC65N Miniature Circuit Breaker, B/C/D Curve
Schneider Electric Acti9 Pro iC65N miniature circuit breaker for AC 50/60Hz low-voltage distribution systems, providing short-circuit protection, overload protection, isolation function, fault trip indication, and B/C/D tripping curves
The Schneider Electric Acti9 Pro iC65N miniature circuit breaker is designed for AC 50/60Hz low-voltage distribution systems. It provides short-circuit protection, overload protection and isolation control for electrical circuits. The product complies with GB/T10963.1 and IEC 60898-1 standards, and features clear fault trip indication. The front window displays a red indicator when the circuit breaker trips due to a fault.
The iC65N series supports B, C and D tripping curves, allowing selection according to different load types. The rated current range is 1–80A, the rated voltage is up to 500V AC, and the rated short-circuit breaking capacity is 6000A. It is suitable for residential, commercial, industrial and terminal distribution applications.
The product can be mounted on a 35mm standard DIN rail, with flexible installation orientation from 0° to 360°. The circuit breaker body has an IP20 protection rating, and can reach IP40 when installed inside a distribution enclosure. It also offers reliable mechanical and electrical endurance
