Schneider Electric iDT40N Miniature Circuit Breaker, 1-Pole, 20A, Type D, 230V AC, 10 kA Breaking Capacity A9P34620 Acti9

Schneider Electric A9P34620 Miniature Circuit Breaker (MCB) from the Acti9 iDT40N series is engineered for superior circuit protection in industrial, commercial, and residential applications. This 1-pole MCB is rated for 20A current and provides Type D tripping characteristics, making it ideal for installations where higher inrush currents are expected such as motor loads.

Operating at a rated AC voltage of 230V, this breaker can safely interrupt fault currents with a breaking capacity of up to 10 kA, protecting electrical wiring and equipment from damage due to overload or short circuit. The thermal magnetic tripping mechanism combines thermal protection against overloads with magnetic response to short circuits, ensuring rapid disconnection under fault conditions.

The device features a toggle switch actuator for easy manual resetting. Its compact dimensions (85mm height, 74mm width, 85mm depth) allow efficient use of panel space and installation on standard DIN rails using the robust mounting design. The screw-type terminals provide secure and reliable wiring connections while the IP20 rating offers protection against intrusion of solid objects.

Manufactured in France, this miniature circuit breaker conforms to international standards including RoHS, REACH, CE, EN IEC 60947-2, and EN IEC 60898-1 assuring compliance with safety and environmental directives. The Acti9 iDT40N range also includes a range of B, C, and D curve options; this model represents the Type D characteristic, suitable for specific high inrush demand applications.

Typical use cases include industrial motor protection, lighting circuits, HVAC equipment, manufacturing plants, and building electrical panels requiring high reliability and safety conformity.
