Product Overview
The iC65L MA circuit breaker belongs to the Acti9 Pro series of miniature circuit breakers. It is an instantaneous, magnetic-only circuit breaker designed in accordance with GB/T 14048.2 and IEC/EN 60947-2 standards, and is suitable for AC 50/60Hz low-voltage terminal distribution systems. The product provides short-circuit protection and isolation function. 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 iC65L MA can be used together with thermal relays or motor starters to achieve overload protection, making it suitable for motor protection applications. This product is suitable for medical IT distribution systems, motor protection, building fire protection systems, and other low-voltage terminal distribution applications. It is available in 2P and 3P configurations, with rated currents from 1.6A to 63A. The breaking capacity can reach up to 20kA. The product can be mounted on a 35mm standard DIN rail and supports flexible installation direction.
