Why Choose the ABB MBA160ALA OT/S750 Module Expansion 1PW?
The ABB MBA160ALA is a CombiLine load-break switch module expansion kit designed for integrating switching equipment into professional low-voltage distribution assemblies. Supplied under ABB order code 2CPX041803R9999, this 1PW module is supplied unpopulated and is intended for compatible ABB OT switching equipment or an ABB S750DR selective main circuit breaker.
The MBA160ALA provides a 160 A module arrangement with a usable equipment width of 216 mm. Compatible equipment is mounted on 35 × 15 mm DIN rails, while the closed plastic cover provides a clean protective front without a device cut-out. The module supports compatible 3-pole or 4-pole equipment configurations.
With dimensions of 300 × 250 × 200 mm, the MBA160ALA occupies two grid units and one field width while providing 24 space units. Its compact format makes it suitable for incorporating a main switching or selective protection function into ABB CombiLine distribution systems without requiring a larger multi-field module.

Reliable Switching Integration for Distribution Assemblies
Load-break switching and selective main-circuit protection are important functions within low-voltage distribution systems, providing controlled switching, isolation or upstream protection according to the equipment selected. The ABB MBA160ALA provides the modular interior arrangement required to incorporate compatible ABB equipment into a structured CombiLine assembly.
Its 160 A rating, DIN-rail equipment mounting and compact single-field-width construction make the MBA160ALA particularly useful where panel builders need to integrate a main switching function without unnecessarily increasing assembly size. The closed cover and modular mounting-frame compatibility also support an organised and consistent finished distribution-board layout.
Typical Applications
- Low-voltage electrical distribution boards.
- Commercial and industrial switchboards.
- Main switching and isolation sections.
- Selective main-circuit protection sections.
- Main and sub-distribution assemblies.
- Electrical panel building and system integration.
- ABB CombiLine interior expansion systems.
