System pro E power 185mm main distribution busbar system

A solution designed to optimize space, simplify assembly and ensure consistent reliability

A compact enclosure footprint with optimized internal copper connections enables efficient use of space in all installation environments.

Its architecture is rooted in IEC 61439-1/-2 design principles and combines modularity with compact dimensions, reducing raw material usage while enabling faster assembly and smooth configuration. With its central busbar layout, compatibility with ABB protection devices and a wide range of enclosure options, the 185 mm system is a dependable and scalable choice for standard distribution requirements across commercial and industrial environments.

Space‑Saving Architecture

The compact design of the 185 mm system allows users to maximize installation space by combining a central main busbar layout with optimized copper routing, reducing overall system dimensions and enabling up to 50% copper savings without compromising electrical performance.

Ease and Speed of Installation

The platform accelerates installation thanks to standardized kits that mount directly on the WR frame, generous wiring areas that simplify cable management, and adaptable plastic components that panel builders can modify directly, allowing a smooth assembly process in any configuration.

Reliable and Cost‑Effective Performance

Engineered to deliver dependable operation with short‑circuit withstand capability up to 75 kA, the system provides a robust and affordable distribution solution where devices can be mounted directly on the main busbar, reducing copper lengths, lowering costs and ensuring reliable operation even in environments requiring protection up to IP55.

Every element—from enclosure dimensions to electrical ratings and protection levels—has been engineered to meet the needs of typical low‑voltage distribution systems, ensuring predictable behavior, easy integration with ABB devices and confidence during installation and operation. This section summarizes the key specifications that define the system’s performance envelope and help designers plan installations with accuracy and consistency.

Up to 2000A rated current

Up to 75kV short circuit current

Footprint optimization thanks to width section designed to optimize breaker dimensions

IP protection class 30, 40, 54, 55

External height of 1900, 2200mm and a depth of 400 and 600 mm.

How the 185 mm System Enhances Main Distribution Applications

Evolving from ABB’s empty enclosure platform, the System pro E Power 185 mm introduces a streamlined architecture where the main busbar also serves as the distribution busbar, significantly simplifying the switchgear layout.

This simplification reduces copper usage and assembly time, making the system ideal for projects where efficiency, repeatability and cost control are essential. The system excels in scenarios requiring dependable but not high‑end performance: installations with only front access, standard protection needs, and panel builders who value modular kits, predictable layouts, and straightforward configuration. By integrating seamlessly with ABB’s breakers and Combiline‑N modules, the 185 mm system offers a flexible, reliable and cost‑optimized approach to power distribution.
