Application

Suitable for applications such as industrial applications, commercial buildings, data centres and e-mobility by reducing downtime and increasing service continuity.

Description

Fully compatible with the existing ABB's System pro M compact® accessories, the S300 P ensures reliable protection in demanding applications such as industrial applications, commercial buildings, data centers and e-mobility by reducing downtime and increasing service continuity.

Other functionalities include the Trip Position Indicator (TPI), the Dual DIN-rail clip, and a QR code for quick access to documentation, certificates, and technical data.


Features and benefits:

Flexibility:

  • Fully compatible with existing System pro M compact® accessories.
  • Easy and quick replacement of old S200 P.
  • Wide range for many different applications and functions.

Simplicity:

  • Updated terminal design supports larger cables, up to 35 mm².
  • New tool-free dual DIN-rail clip for easy removal of the device, even when mounted on busbars.
  • One module width, in combination with built-in auxiliary contact, to save installation space.

Innovation:

  • Simple access to product data and documents via QR code.
  • New Trip Position Indicator (TPI) to identify tripping events (e.g. overload, short-circuit).
  • Increased impulse withstand voltage and lower internal resistance for improved safety and energy efficiency thanks to reduced power loss.

Performance:

  • Worldwide usability with global certifications.
  • High level of 25 kA of overcurrent and short circuit protection
  • for the complete MCB range (0.2–63 A).
  • Best-in-class technical features for improved robustness and safety.

Sustainability:

  • Part of the ABB EcoSolutions™ portfolio. The ABB EcoSolutions™ label provides full transparency to environmental impacts across the entire product lifecycle. Products within the portfolio comply with a set of key performance indicators defined in ABB’s circularity framework and carry an external, third-party verified environmental product declaration (ISO 14025).
