Why Choose the ABB MA250A Universal Switch Expansion 1PW?
The ABB MA250A, order code 2CPX041387R9999, is a mounted CombiLine universal switch expansion module designed for ABB electrical sub-distribution systems. Part of the ABB CombiLine N interior expansion system and the DESUJ Sub Distribution product group, it provides a flexible installation platform for different types of switching equipment within professional low-voltage distribution cabinets.
The MA250A has a 2 RE / 300 mm height and a single-field width of 250 mm, providing 24 space units. Its equipment area offers a 170 mm useful width and 122 mm useful depth, with deep cross beams allowing variable adjustment to accommodate different compatible devices.
Supplied unequipped for the installation of one universal switch, the MA250A supports a maximum rated current of 250 A. Equipment is secured using cage nuts, while a closed plastic cover with a 90-degree press-and-turn closure and RAL 7035 light-grey finish provides a clean cabinet front. The module is suitable from a cabinet depth of 200 mm and can be used with ABB EDF or WR mounting frames.

Flexible Universal Switch Integration
Universal switch modules provide adaptable mounting space where distribution-board equipment cannot be accommodated by a device-specific module. The ABB MA250A combines a 170 mm useful width with a 122 mm useful depth and variable deep cross beams, allowing compatible switching and protective equipment to be positioned securely within a CombiLine N cabinet.
With a maximum rated current of 250 A and a compact 250 mm single-field-width format, the MA250A is well suited to commercial and industrial distribution assemblies requiring flexible equipment integration. Its closed cover, cage-nut mounting system and compatibility with both EDF and WR mounting frames provide a versatile solution for customised low-voltage cabinet construction.
Typical Applications
- Commercial and industrial sub-distribution boards.
- Universal switch and switch-disconnector installations.
- Circuit-breaker integration in distribution assemblies.
- Electrical distribution cabinets and switchboards.
- Customised low-voltage switching applications.
- Building-services electrical distribution systems.
- ABB CombiLine N cabinet expansion and interior fit-out.
