Why Choose the ABB MS127 Busbar Module Expansion 1PW?
The ABB MS127, order code 2CPX041275R9999, is a mounted CombiLine horizontal busbar module designed for ABB electrical sub-distribution systems. Part of the ABB CombiLine interior expansion system and the DESUJ Sub Distribution product group, it provides a structured mounting solution for a three-pole horizontal busbar system with a maximum rated current of 630 A.
The MS127 has a 2 RE / 300 mm height and a single-field width of 250 mm, providing 24 space units. It is designed for a horizontal three-pole busbar arrangement with a 60 mm busbar centre distance and incorporates an ABB ZX151 busbar holder for secure positioning of the conductors.
The module accommodates up to three copper busbars, which are ordered separately, and supports suitable busbars up to 30 × 5 mm for a maximum rated current of 630 A. Closed plastic covers with 90-degree press-and-turn closures provide protection across the module, while the RAL 7035 light-grey finish integrates with the wider CombiLine system. The MS127 is suitable from a cabinet depth of 215 mm and requires an ABB EDF or WR mounting frame.

High-Current Busbar Distribution for Electrical Cabinets
Busbar systems provide an efficient method of distributing high electrical currents through switchboards and sub-distribution assemblies while maintaining an organised and modular cabinet layout. The ABB MS127 provides the supporting structure for a horizontal three-pole busbar system, allowing compatible copper conductors to be integrated into the CombiLine interior expansion system.
With a maximum rated current of 630 A, a 60 mm busbar centre distance and capacity for three copper rails, the MS127 is suited to demanding commercial and industrial distribution applications. Its compact 250 mm field width allows high-current distribution to be incorporated efficiently within ABB CombiLine cabinets while retaining compatibility with EDF and WR mounting frames.
Typical Applications
- Commercial and industrial sub-distribution boards.
- High-current electrical distribution cabinets.
- Three-pole horizontal busbar systems.
- Switchboards and power distribution assemblies.
- Building-services electrical distribution systems.
- ABB CombiLine cabinet expansion and interior fit-out.
