Why Choose the ABB M301P-D4 Magnetic Circuit Breaker?
The ABB M301P-D4 is a compact single-pole magnetic-only circuit breaker designed to provide dedicated short-circuit protection for industrial electrical circuits. With ABB order code 2CDA381799R0041, this device forms part of ABB's S200M / S300P circuit-protection portfolio and is intended for applications where overload protection is coordinated separately.
Featuring a Type D magnetic characteristic and a rated current of 4 A, the M301P-D4 is particularly suitable for circuits where comparatively high temporary inrush currents can occur during normal energisation. This makes it useful for industrial equipment, transformers, control circuits and other inductive loads where a magnetic-only protection strategy is required.
The M301P-D4 combines a single-pole configuration with a 25 kA breaking-capacity rating, providing robust short-circuit protection in a compact modular format. Its DIN-rail construction makes it straightforward to integrate into industrial control panels, distribution assemblies and coordinated electrical protection systems.
Key Advantages
- Magnetic-only short-circuit protection for coordinated industrial circuit protection.
- 4 A rated current for lower-current equipment and control circuits.
- Type D magnetic characteristic suitable for circuits with comparatively high inrush currents.
- 25 kA breaking-capacity rating for robust short-circuit protection.
- Suitable for applications where thermal overload protection is provided separately.
- Compact single-pole DIN-rail construction for efficient panel installation.

Dedicated Magnetic Short-Circuit Protection for Industrial Circuits
Unlike a conventional thermal-magnetic miniature circuit breaker, the ABB M301P-D4 is intended to provide magnetic short-circuit protection rather than thermal overload protection. This allows the short-circuit and overload protection functions to be coordinated independently within an industrial electrical system.
Its Type D magnetic characteristic is suited to circuits that experience comparatively high short-duration inrush currents during normal start-up. This makes the M301P-D4 a practical solution for appropriately engineered industrial equipment, transformers, inductive loads and control systems where dedicated magnetic protection is required.
Typical Applications
- Industrial electrical control panels.
- Dedicated short-circuit protection circuits.
- Industrial circuits with separately coordinated overload protection.
- Transformers and inductive electrical loads.
- Equipment with comparatively high temporary inrush currents.
- Industrial distribution and automation systems.
