Schneider Electric Acti9 Pro iDPNa-S miniature circuit breaker for overload protection, short-circuit protection and control of terminal circuits. It can disconnect both phase and neutral conductors, with isolation protection function
Schneider Electric Acti9 Pro iDPNa-S miniature circuit breaker is designed for terminal distribution circuits, providing overload protection, short-circuit protection and circuit control. The product can disconnect both the phase conductor and the neutral conductor at the same time, while the neutral conductor does not provide protection. It is suitable for low-voltage distribution applications in residential buildings, commercial buildings and terminal distribution boxes.
The product complies with GB10963.1 and IEC 60898-1 standards, and supports isolation protection function. It adopts a 1P+N pole configuration, with a rated current range of 6–40A, operating voltage of 230V, breaking capacity of 4500A, and service breaking capacity Ics of 100%.
The product supports C and D tripping curves, allowing selection according to different load types. The circuit breaker body has an IP20 protection rating, and can reach IP40 when installed inside a distribution box. It provides stable electrical and mechanical endurance.
