Why Choose the ABB MA250ALAB OT250E03P Switch Expansion 1PW?
The ABB MA250ALAB is a CombiLine load-break switch expansion module designed for switching and isolation within low-voltage distribution cabinets. Supplied under ABB order code 2CPX041372R9999, the module is factory-equipped with one ABB OT250E03P 3-pole load-break switch.
The MA250ALAB has a module height of 2 RE / 300 mm, a field width of 1 FB / 250 mm and provides 24 space units. Its integrated OT250E03P switch has a rated current of 250 A, providing a compact switching solution within a single CombiLine field width.
Designed for cabinets from 200 mm depth, the module features plastic covers with a dedicated equipment cut-out, RAL 7035 finish and 90-degree press-and-turn fasteners. The load-break switch is mounted on a mounting cross beam, while the required EDF or WR mounting frame must be ordered separately.
Key Advantages
- Factory-equipped with an ABB OT250E03P load-break switch.
- 250 A rated current for substantial low-voltage switching applications.
- 3-pole configuration suitable for three-phase switching and isolation.
- Compact 1PW / 250 mm field width helps optimise cabinet space.
- Mounted CombiLine module reduces separate mechanical integration requirements.
- Compatible with both EDF and WR mounting frames.

- RAL 7035 cover finish.
- Suitable for cabinets from 200 mm depth.
- Suitable for expansion on EDF or WR mounting frames.
The ABB MA250ALAB combines the CombiLine modular interior system with an installed OT250E03P 3-pole load-break switch. This arrangement provides a dedicated switching and isolation point for three-phase low-voltage distribution without requiring the switch to be mechanically integrated into an empty module separately.
Its compact 250 mm field width, 300 mm module height and 24 space units make the MA250ALAB suitable where efficient use of cabinet space is important. The module is supplied populated and mounted for cabinet installation, while the appropriate EDF or WR mounting frame must be selected and ordered separately.
Typical Applications
- Low-voltage power distribution cabinets.
- ABB CombiLine sub-distribution assemblies.
- Three-phase load switching and isolation.
- Main and distribution switching sections.
- Commercial and industrial electrical panels.
- Professional switchboard and panel-building projects.
