Why Choose the ABB MA630A Universal Switch Expansion 2PW?
The ABB MA630A, order code 2CPX041388R9999, is a universal switch expansion module designed for ABB electrical sub-distribution systems. Part of the ABB CombiLine installation system and the DESUJ Sub Distribution product group, it provides a flexible platform for integrating compatible switching and protective equipment into professional low-voltage distribution cabinets.
The MA630A uses a two-panel-width (2PW) configuration, providing additional installation space for larger switching equipment compared with single-panel-width universal modules. Its adaptable design makes it suitable where a dedicated device-specific expansion module is not appropriate and a flexible mounting solution is required.
Designed for professional switchboard and distribution-board construction, the MA630A supports organised integration of switching equipment while retaining the modular architecture of the ABB CombiLine system. The universal format makes it particularly useful for customised commercial and industrial distribution assemblies requiring a larger equipment installation area.

Flexible Universal Switch Integration
Universal switch modules provide adaptable installation space for switching and protective equipment that may not correspond to a dedicated device-specific module. The ABB MA630A provides a two-panel-width platform for this purpose, allowing compatible equipment to be incorporated into a structured CombiLine distribution assembly.
The larger 2PW format makes the MA630A particularly suitable for customised low-voltage cabinet layouts where additional equipment space is required. This flexibility supports commercial and industrial switchboard designs while maintaining the organised, modular construction associated with ABB CombiLine sub-distribution systems.
Typical Applications
- Commercial and industrial sub-distribution boards.
- Universal switch and switching-device installations.
- Protective-device integration in distribution assemblies.
- Electrical distribution cabinets and switchboards.
- Customised low-voltage switching applications.
- Building-services electrical distribution systems.
- ABB CombiLine cabinet expansion and interior fit-out.
