ABB S301P-D1NA MCB – 1P+N – D Curve – 1A – 25kA

Why Choose the ABB S301P-D1NA Miniature Circuit Breaker?

The ABB S301P-D1NA is a robust and high-performance miniature circuit breaker (MCB) designed to protect electrical installations against overloads and short circuits. As part of the ABB System pro M compact S300P series, it is developed for demanding industrial installations where dependable circuit protection and high short-circuit performance are required.

This 1P+N circuit breaker provides a D-type tripping characteristic, making it suitable for circuits where higher inrush currents can occur. Both the phase and neutral conductors are accommodated in the compact modular device, with the neutral pole switched alongside the protected phase pole. DIN-rail mounting enables straightforward installation within electrical distribution and control systems.

With a rated current of 1 A and a rated breaking capacity of 25 kA, the S301P-D1NA provides high-level protection for AC electrical circuits. Its 1P+N configuration is suitable for control circuits, machinery and distribution applications where both the phase and neutral conductors require coordinated switching.

Reliable Circuit Protection for Industrial Electrical Systems

Miniature circuit breakers such as the ABB S301P-D1NA protect electrical circuits by automatically interrupting the supply when an overload or short circuit occurs. The D-type characteristic is particularly suited to applications where equipment can produce comparatively high transient or starting currents.

The S300P series is designed for industrial installations and combines compact modular construction with high short-circuit interruption capability. Its 1P+N configuration provides protection and switching for the phase conductor while the neutral pole is switched alongside it.

Typical Applications

• Industrial distribution boards and switchboards.
• Electrical control panels and automation systems.
• Machinery and industrial equipment circuits.
• Control and auxiliary circuits with higher inrush currents.
• Commercial and industrial electrical installations.
• AC circuit protection requiring coordinated phase and neutral switching.
