Why Choose the ABB S301P-D0.5NA?

The ABB S301P-D0.5NA is a high-performance miniature circuit breaker from the System pro M compact S300P series, designed to provide dependable protection against overloads and short circuits in AC electrical installations.

This 1P+N miniature circuit breaker combines a 0.5 A rated current with a D tripping characteristic and a high 25 kA rated breaking capacity, making it suitable for applications requiring precise circuit protection and controlled circuit interruption.

The switched-neutral configuration disconnects both the phase and neutral conductors as required, while the compact DIN-rail design supports straightforward installation in distribution boards and control panels.

Key Advantages

  • High breaking capacity: Provides a rated breaking capacity of 25 kA for robust short-circuit protection.
  • D tripping characteristic: Suitable for circuits where higher instantaneous current levels can occur during equipment starting or operation.
  • 1P+N configuration: Protects the live conductor while providing switched-neutral isolation.
  • 0.5 A rated current: Provides low-current circuit protection for sensitive AC control and auxiliary circuits.
  • DIN-rail mounting: Enables convenient installation in compatible electrical distribution and control equipment.
  • System pro M compact platform: Forms part of ABB's S300P range for modular low-voltage circuit protection.

  • DIN-rail mounting

Reliable Circuit Protection for Industrial Electrical Systems

The S301P-D0.5NA is designed for electrical distribution and control applications where reliable miniature circuit protection is required. Its D characteristic accommodates circuits that may experience higher transient currents while maintaining protection against excessive current conditions.

With its 1P+N switched-neutral arrangement and 25 kA breaking capacity, the breaker provides a practical solution for installations requiring both circuit protection and controlled isolation of the phase and neutral conductors.

Typical Applications

  • Industrial control panels and electrical distribution boards
  • Automation and control circuits
  • Low-current AC control and auxiliary circuits
  • Electrical machinery and equipment control systems
  • Commercial and industrial building services
  • Applications requiring D-characteristic miniature circuit protection
