Why Choose the ABB S301P-B8 Miniature Circuit Breaker?

The ABB S301P-B8 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 single-pole circuit breaker provides a B-type tripping characteristic, making it suitable for general-purpose resistive and low-inrush electrical circuits. Its compact modular construction allows straightforward installation within electrical distribution and control systems, while the DIN-rail mounting format supports efficient panel assembly.

With a rated current of 8 A and a rated breaking capacity of 25 kA, the S301P-B8 provides high-level protection for AC electrical circuits. Its compact single-pole format makes it suitable for control circuits, lighting, distribution and industrial applications where dependable overcurrent protection is required.

Key Advantages

  • Compact single-pole miniature circuit breaker for industrial applications.
  • 8 A rated current for reliable circuit protection.
  • B tripping characteristic suitable for general-purpose circuits with low inrush currents.
  • 25 kA rated breaking capacity for high short-circuit protection performance.
  • Single protected pole with no neutral pole.
  • DIN-rail mounting for straightforward installation in electrical distribution equipment.

Key Features

  • ABB System pro M compact S300P series.
  • S301P-B8 type designation.
  • 8 A rated current.
  • B tripping characteristic.
  • 1-pole configuration with no neutral pole.
  • 25 kA rated breaking capacity.
  • Designed for AC electrical systems.
  • DIN-rail mounting for modular electrical installations.

Reliable Circuit Protection for Industrial Electrical Systems

Miniature circuit breakers such as the ABB S301P-B8 protect electrical circuits by automatically interrupting the supply when an overload or short circuit occurs. The B-type characteristic is suited to general-purpose circuits where relatively low transient or starting currents are expected.

The S300P series is designed for industrial installations and combines compact modular construction with high short-circuit interruption capability. Its single-pole configuration provides protection for an individual AC circuit conductor without a switched neutral pole.

Typical Applications

  • Industrial distribution boards and switchboards.
  • Electrical control panels and automation systems.
  • Lighting and general-purpose electrical circuits.
  • Control and auxiliary circuits with low inrush currents.
  • Commercial and industrial electrical installations.
  • General AC circuit protection requiring a B-type characteristic.
