Why Choose the ABB M304P-D50 Magnetic Circuit Breaker?
The ABB M304P-D50 is a high-performance four-pole magnetic-only miniature circuit breaker designed to provide dependable short-circuit protection for demanding industrial electrical installations. As part of the ABB M300P series, it combines a 50 A rated current, D characteristic and high 25 kA breaking capacity in a compact modular format.
Unlike conventional thermal-magnetic circuit breakers, the M304P-D50 provides magnetic-only protection, making it suitable for circuits where short-circuit protection is required while overload protection is provided separately. Its four-pole configuration enables coordinated switching and protection across four conductors in suitable industrial electrical systems.
With a rated current of 50 A and a 25 kA breaking capacity, the M304P-D50 is designed for demanding industrial control, machinery and distribution applications. Its D characteristic makes it suitable for circuits that can experience higher transient or inrush currents during normal operation.
Key Advantages
- Reliable magnetic-only short-circuit protection for industrial electrical systems.
- 50 A rated current for higher-current industrial circuits.
- Four-pole configuration for multi-pole circuit protection and isolation.
- D characteristic suitable for circuits subject to higher transient or inrush currents.
- High 25 kA short-circuit breaking capacity.
- Compact modular construction for electrical panels and machinery.

Reliable Magnetic Short-Circuit Protection
Magnetic-only circuit breakers such as the ABB M304P-D50 respond rapidly to high fault currents without incorporating conventional thermal overload tripping. This allows short-circuit protection to be coordinated with a separate overload protection device selected for the connected equipment and application.
The M300P series provides a compact solution for industrial installations requiring dependable operation and high short-circuit breaking performance. The four-pole M304P-D50 is particularly suitable for machinery, control and distribution systems requiring coordinated multi-pole protection and the ability to accommodate high transient currents.
Typical Applications
- Industrial three-phase electrical systems.
- Machinery and automation control panels.
- Motor circuits with separate overload protection.
- Industrial distribution and control systems.
- Manufacturing and production equipment.
- Circuits subject to high transient or starting currents.
