The Schneider Electric Acti9 iC65 miniature circuit breaker family provides final-circuit overload and short-circuit protection in 1P, 2P, 3P and 4P configurations. The supplied product content covers three performance segments: iC65N at 6 kA, iC65H at 10 kA and iC65L at 15 kA. Rated current is 1–80 A for iC65N/H and 1–63 A for iC65L.
The Schneider Electric Acti9 iC65 Miniature Circuit Breaker (MCB) is designed to provide reliable overload and short-circuit protection for low-voltage electrical distribution systems. Available in multiple breaking capacity versions, including iC65N, iC65H and iC65L, the series offers flexible current ratings, pole configurations and tripping characteristics to meet different circuit protection requirements. With a compact modular design, DIN-rail mounting and clear contact status indication, Acti9 iC65 circuit breakers are suitable for residential, commercial and industrial electrical installations.
The Acti9 iC65 series uses thermal-magnetic tripping technology to protect electrical circuits against overloads and short-circuit faults. Available B, C and D tripping curves accommodate different load characteristics, allowing users to select appropriate protection for lighting circuits, general electrical equipment and loads with higher starting currents. The circuit breakers also provide an isolation function, supporting safe disconnection during electrical inspection and maintenance.
The iC65 family includes different versions to accommodate varying short-circuit protection requirements:
iC65N: Standard breaking capacity for general low-voltage distribution applications.
iC65H: Higher breaking capacity for installations with greater prospective short-circuit currents.
iC65L: High breaking capacity for applications requiring enhanced short-circuit interruption performance.
Breaking capacity ratings depend on the specific model, rated voltage and applicable product standard. These options allow the iC65 series to be selected for different electrical distribution environments.
Designed for modular electrical distribution boards, the Acti9 iC65 series supports 1P, 2P, 3P and 4P configurations, with installation on standard 35 mm DIN rails. Its double locking clip structure facilitates installation and removal, while the flexible wiring arrangement supports both top-feed and bottom-feed connections.
The VisiSafe contact position indicator provides a clear visual indication of the open contact position, while the VisiTrip window displays a red indication when the circuit breaker trips due to an electrical fault. Fast closing and current-limiting technology further support reliable circuit operation. Compatible electrical accessories are available for remote indication of circuit breaker status.
The Acti9 iC65 MCB series is suitable for branch circuit protection in residential buildings, commercial facilities, industrial plants and electrical control panels. Typical applications include lighting distribution, socket circuits, small power equipment and industrial auxiliary circuits. Its different breaking capacity versions and tripping characteristics allow integration into various low-voltage power distribution systems.
The Acti9 iC65 series offers multiple configurations to accommodate different installation and protection requirements. Key selection parameters include:
