Schneider Electric Acti9 Acti9 iDT40K Miniature Circuit Breaker, 3+N-Pole, 10A, Type C, 400V AC, 4500A Breaking A9P71710

Schneider Electric A9P71710 Miniature Circuit Breaker is part of the Acti9 iDT40K series designed for industrial, commercial, and residential electrical protection applications. It features a 3+N pole configuration allowing simultaneous phase and neutral protection, rated at 10 amps with type C tripping characteristic suitable for moderately inductive loads.

This miniature circuit breaker uses a thermal-magnetic trip mechanism to provide rapid disconnection under overloads or short circuits, ensuring system safety and equipment protection. It has a breaking capacity of 4500 A at 400V AC, conforming to international standards EN/IEC 60898-1 and EN/IEC 60947-2, making it suitable for global electrical installations.

Built to be mounted on a standard DIN rail, this device features a toggle switch reset actuator for intuitive ON/OFF operation and includes a trip indicator for quick fault identification. The terminal type is tunnel style, allowing secure wiring connections. Its compact dimensions (85mm height, 54mm width, 74mm depth) enable efficient space usage within electrical distribution boards.

Schneider Electric has constructed this circuit breaker for high electrical durability, rated to 20,000 electrical cycles. It resists impulse voltages up to 4 kV and operates reliably in ambient temperatures ranging from -25°C to 70°C with 95% relative humidity tolerance. The padlockable feature enhances operational safety during maintenance by preventing accidental re-closure.

Originating from Hungary, the product carries Schneider Electric’s Green premium classification, emphasizing energy efficiency and environmental considerations. Typical use cases include industrial power distribution, commercial electrical panels, HVAC systems, manufacturing setups, and reliable circuit protection in laboratory and residential environments.
