Why Choose the ABB S301P-D32NA Miniature Circuit Breaker?
The ABB S301P-D32NA is a compact and reliable miniature circuit breaker (MCB) designed to provide dependable protection against overloads and short circuits in industrial and commercial electrical installations. As part of the ABB System pro M compact S300P series, it combines a D tripping characteristic with a high 25 kA rated breaking capacity for demanding circuit protection applications.
The S301P-D32NA features a 1P+N configuration with switched neutral, allowing the live conductor and neutral to be switched as part of the circuit protection arrangement. Its thermal-magnetic overcurrent protection and compact modular construction make it suitable for professional electrical distribution, control panels and equipment installations.
With a 32 A rated current, D tripping characteristic and 25 kA rated breaking capacity, the S301P-D32NA is suitable for circuits where higher starting or inrush currents may occur. DIN-rail mounting supports straightforward integration into suitable distribution boards and electrical assemblies.

Reliable Overcurrent Protection with Switched Neutral
The ABB S301P-D32NA combines thermal and magnetic protection to disconnect a circuit when excessive current conditions occur. The thermal mechanism responds to sustained overload conditions, while the magnetic protection provides rapid interruption during short-circuit events.
The D tripping characteristic is intended for applications where circuits can experience comparatively high transient or starting currents. This makes the S300P D-characteristic range suitable for selected industrial loads and equipment where reliable circuit protection is required alongside tolerance of higher inrush currents. The switched neutral configuration provides simultaneous switching of the live circuit path and neutral.

- Industrial and commercial electrical distribution systems.
- Control circuits and control panels.
- Industrial automation installations.
- Machinery and manufacturing equipment.
- Electrical circuits with higher inrush currents.
- Switchboards and distribution assemblies.
- OEM machinery and professional electrical installations.
