Circuit breaker Schneider Electric Acti9 iC60N 1-pole 40 A C characteristic A9K02140

Schneider Electric Acti9 iC60N single-pole miniature circuit breaker rated 40 A with C tripping characteristic is designed to provide reliable overload and short-circuit protection in residential and commercial electrical installations. The compact DIN-rail mountable device is intended for distribution circuits such as lighting, socket outlets and small motors where a C curve response is required to tolerate brief inrush currents while still protecting conductors and equipment from sustained faults.

Advantages

This 1-pole breaker offers compact dimensions and standardized DIN-rail mounting for straightforward integration into distribution boards. The type C trip curve provides balanced sensitivity for general-purpose circuits, allowing higher inrush currents from motors or fluorescent lamp starters without nuisance tripping while ensuring timely disconnection for overloads and short circuits. The device is built to industry standards for mechanical and electrical durability and simplifies branch-circuit protection with a clear current rating and switching operation.

Suitable for

• Residential lighting and socket circuits
• Small commercial distribution boards
• Protection of small motors and pump circuits with moderate inrush
• Retrofit or new installations with DIN-rail distribution enclosures

Key specifications

• Poles: single-pole (1P)
• Rated current: 40 A
• Tripping characteristic: type C (moderate inrush tolerance)
• Mounting: DIN-rail
• Function: thermal-magnetic short-circuit and overload protection
• Application: branch-circuit protection for lighting, sockets and small motors

How to use

Install the breaker on a standard DIN-rail inside a compatible distribution board, ensuring correct orientation and secure terminal connections for line and load conductors. Size conductors and upstream protective devices according to applicable wiring regulations and the 40 A rated current. After installation, test switching operation and verify downstream circuit continuity before energizing the protected circuit. Use appropriate personal protective equipment and follow local electrical codes when performing installation or maintenance.

Usage recommendations

For correct circuit protection, select this C characteristic breaker where motor starting currents or inrush from lighting fixtures are expected. Verify coordination with upstream protective devices and confirm conductor ampacity for continuous loads near the 40 A rating. For circuits with higher inrush or special protection requirements, evaluate alternative trip characteristics or additional protective equipment.
