Why Choose the ABB MBH250 S700/750 Expansion 2PW?
The ABB MBH250 is an unpopulated S700/750 expansion module designed for ABB low-voltage sub-distribution assemblies. Part of the ABB CombiLine system and DESUJ Sub Distribution range, it provides a dedicated internal installation field for ABB S700 selective main circuit breakers.
The MBH250 incorporates a 40 mm busbar system with horizontally arranged busbars and ZB5 busbar holders. It accommodates up to four copper busbars, which are ordered separately, and is designed for ABB S700 devices from 1 to 4 poles with a maximum rated current of 250 A.
Configured for 2 panel widths (2PW), the MBH250 measures 300 × 500 × 200 mm and provides 48 space units. Its usable widths are 210/105 mm, and it can be installed on either an EDF or WR mounting frame in cabinets from 200 mm depth.

S700 Distribution for CombiLine Systems
The ABB MBH250 provides a dedicated installation field for ABB S700 selective main circuit breakers within CombiLine low-voltage distribution assemblies. Its horizontal busbar system uses a 40 mm centre distance and ZB5 holders, providing a structured connection platform with a maximum rated current of 250 A.
Because the MBH250 is supplied unpopulated and without copper busbars, the required S700 devices and busbars can be selected separately to suit the distribution configuration. Its 2PW format, 48 space units and EDF or WR mounting-frame compatibility make it suitable for modular sub-distribution cabinet construction.
Typical Applications
- Low-voltage electrical distribution boards.
- ABB CombiLine cabinet systems.
- ABB S700 selective main circuit breaker installations.
- Main and sub-distribution assemblies.
- Commercial and industrial electrical panels.
- Modular busbar distribution systems.
