Why Choose the ABB MBH150 S700/750 Expansion 1PW?
The ABB MBH150 is a modular 40 mm busbar system expansion kit for ABB S700 main circuit breakers, designed for ABB CombiLine N electrical distribution systems. Supplied under ABB order code 2CPX041792R9999, this unassembled interior fitting module provides a dedicated solution for integrating S700 main circuit breakers into compatible low-voltage sub-distribution assemblies.
The MBH150 is supplied unequipped and is designed for ABB S700 1- to 4-pole main circuit breakers, with a width of 35 mm per pole. It incorporates a ZB5 busbar holder and supports horizontally arranged busbars with a 40 mm centre-to-centre spacing. Up to four copper busbars can be accommodated, with the busbars ordered separately.
With a 2 GU / 300 mm height and 1 PW / 250 mm field width, the MBH150 provides 24 space units and a usable equipment width of 105 mm. The module supports a maximum rated current of 250 A and is suitable for cabinets from 200 mm depth, using a separately ordered EDF or WR mounting frame.

Reliable S700 Main Circuit Breaker Integration
The ABB MBH150 provides the modular infrastructure required to integrate S700 main circuit breakers with a 40 mm busbar system inside a CombiLine N distribution assembly. Its ZB5 busbar holder maintains the required horizontal busbar arrangement, while the equipment cut-out allows the installed breaker to remain accessible from the front of the assembly.
With support for 1- to 4-pole S700 devices, up to four copper busbars and a maximum rated current of 250 A, the MBH150 provides a compact solution for incoming and main circuit protection. Its 1 PW format is particularly useful where efficient use of enclosure space is important in commercial and industrial sub-distribution systems.
Typical Applications
- Electrical sub-distribution boards.
- ABB CombiLine N distribution assemblies.
- ABB S700 main circuit breaker installations.
- 40 mm busbar distribution systems.
- Commercial and industrial low-voltage installations.
- Switchgear and distribution panel construction.
