Why Choose the ABB MBA250ALA OT Module Expansion 1PW?
The ABB MBA250ALA is an OT module expansion designed for integrating compatible ABB switch-disconnector equipment into modular low-voltage distribution assemblies. Supplied under ABB order code 2CPX041804R9999, the MBA250ALA provides a dedicated 1PW section for incorporating an OT switching function into an ABB sub-distribution system.
As part of ABB's DESUJ Sub Distribution product group, the MBA250ALA supports organised panel construction by providing a purpose-designed module for compatible OT equipment. Its modular format allows the switching section to be incorporated alongside other distribution, protection, terminal and busbar modules within a coordinated electrical assembly.
The 1PW configuration is particularly useful where a compact dedicated switching section is required. By providing a defined installation module rather than an improvised mounting arrangement, the MBA250ALA helps panel builders maintain an orderly internal layout and consistent integration with compatible ABB distribution-system components.

Reliable Switching Integration for Distribution Assemblies
Switch-disconnectors provide an important switching and isolation function within low-voltage distribution systems. The ABB MBA250ALA provides a dedicated modular section for incorporating compatible ABB OT equipment into an organised distribution-board or switchboard arrangement.
Using a purpose-designed expansion module helps panel builders maintain consistent equipment positioning and a structured internal layout. The MBA250ALA can therefore form part of a wider ABB modular assembly containing protective devices, terminals, busbar sections and other functional distribution modules.
Typical Applications
- Low-voltage electrical distribution boards.
- Commercial and industrial switchboards.
- Main switching and isolation sections.
- ABB OT switch-disconnector integration.
- Main and sub-distribution assemblies.
- Distribution-board extensions and refurbishment.
- Electrical panel building and system integration.
