The Schneider Electric Acti9 iC60L A9F90376 is a premium 3-Pole (3P), 6.3A Miniature Circuit Breaker (MCB) designed to provide high-performance short-circuit protection for industrial motor control and automation systems. Featuring an MA (Magnetic Only) tripping curve, this MCB delivers instantaneous magnetic tripping without thermal overload protection, making it ideal for motor branch circuit protection when used together with an external thermal overload relay.

Manufactured to IEC/EN 60947-2 standards, the Acti9 iC60L provides a 20kA short-circuit breaking capacity at 400VAC and up to 40kA at 220–240VAC, ensuring reliable protection in demanding industrial environments. Schneider Electric's patented VisiTrip indicator enables rapid fault identification, while the VisiSafe green strip visually confirms that the contacts are physically open, providing enhanced safety during maintenance.

Designed with a fast-closing mechanism independent of manual operation, the Acti9 iC60L delivers exceptional durability with an electrical endurance of 10,000 switching cycles and a mechanical endurance of 20,000 operations. Compact and DIN rail mountable, it is widely trusted by OEMs, panel builders, electrical contractors, automation engineers, and industrial maintenance professionals.
