Why Choose the ABB MBH350 S700/750 Expansion 3PW?
The ABB MBH350 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 MBH350 incorporates a 40 mm horizontal busbar system with ZB5 busbar holders and provision for up to four copper busbars. The copper busbars are ordered separately, while the module is designed for ABB S700 selective main circuit breakers from 1 to 4 poles and supports a maximum rated current of 250 A.
Configured for 3 panel widths (3PW), the MBH350 measures 300 × 750 × 200 mm and provides 72 space units. It offers usable widths of 315/210 mm, incorporates additional central bracing for its three-field width and can be installed on either an EDF or WR mounting frame in cabinets from 200 mm depth.

S700 Distribution for CombiLine Systems
The ABB MBH350 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 MBH350 is supplied unpopulated and without copper busbars, the required S700 devices and busbars can be selected separately to suit the distribution configuration. Its 3PW format, 72 space units and additional central bracing make it suitable for larger modular sub-distribution cabinet layouts.
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.
