Why Choose the ABB MA630ALA OT200/630 Switch Expansion 2PW?
The ABB MA630ALA is a CombiLine N switch-disconnector expansion module designed for ABB OT load-break switches in low-voltage sub-distribution assemblies. Supplied under ABB order code 2CPX041378R9999, this unpopulated module provides a dedicated installation position for compatible OT switching equipment.
As part of the ABB DESUJ Sub Distribution product group, the MA630ALA is designed for professional panel building and structured electrical distribution. It accommodates one compatible ABB OT switch-disconnector in a 3-pole or 4-pole arrangement and uses a mounting cross beam for secure integration into the distribution assembly.
The MA630ALA has a 2PW / 500 mm field width, a height of 450 mm and provides 72 PLE. It supports a maximum rated current of 630 A, is suitable from a cabinet depth of 275 mm and is designed for installation on a WR mounting frame.

High-Capacity OT Switch-Disconnector Integration
The ABB MA630ALA provides a structured installation platform for OT switch-disconnectors within CombiLine N distribution assemblies. Its 630 A maximum rated current makes it suitable for higher-current switching and isolation duties where reliable manual disconnection is required within commercial or industrial low-voltage systems.
With its 2PW format, 72 PLE capacity and dedicated WR mounting-frame arrangement, the MA630ALA supports organised construction of maintainable and expandable ABB distribution panels while providing the space required for larger OT switch-disconnector installations.
Typical Applications
- ABB CombiLine N low-voltage distribution boards.
- OT switch-disconnector installations up to 630 A.
- Commercial and industrial sub-distribution systems.
- Main and sectional electrical isolation.
- Modular switchboards and distribution cabinets.
- Professional panel-building and switchgear applications.
