Why Choose the ABB MBT142 NH1 Fuse Switch Expansion 1PW?
The ABB MBT142 is an unpopulated NH1 fuse switch disconnector 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 installation field for an NH1 fuse switch disconnector within a compact 1PW cabinet section.
The MBT142 is designed for installation of one NH1 fuse switch disconnector, with the ABB ZH431 250 A device specified as a compatible option. The module is designed for a 3-pole busbar system and supports a maximum rated current of 440 A, while the fuse switch disconnector itself is ordered separately.
Configured for 1 panel width (1PW), the MBT142 measures 450 × 250 × 200 mm and provides 36 space units. It corresponds to 3 grid units (RE), features a plastic cover with cut-out and can be installed from a cabinet depth of 200 mm using a separately ordered EDF or WR mounting frame.

NH1 Fused Distribution for CombiLine Systems
The ABB MBT142 provides a dedicated installation field for an NH1 fuse switch disconnector within a CombiLine distribution assembly. Its 3-pole busbar arrangement supports a maximum rated current of 440 A, while the compact 1PW format allows fused outgoing distribution to be integrated efficiently into modular low-voltage cabinets.
Because the MBT142 is supplied unpopulated, the NH1 fuse switch disconnector can be selected separately to suit the assembly requirements. ABB specifies the ZH431, rated up to 250 A, for use with this module, while the EDF or WR mounting frame must also be ordered separately.
Typical Applications
- Low-voltage electrical distribution boards.
- ABB CombiLine cabinet systems.
- NH1 fused outgoing circuits.
- Commercial and industrial power distribution.
- Sub-distribution and switchgear assemblies.
- Modular fused distribution panels.
