Why Choose the ABB MBT136 NH00 Fuse Switch Expansion 1PW?
The ABB MBT136 is a CombiLine NH00 fuse switch-disconnector expansion module kit designed for low-voltage electrical distribution assemblies. Supplied under ABB order code 2CPX041770R9999, this 1PW module is unequipped and prepared for the installation of two NH00 fuse switch-disconnectors, providing a structured solution for fused power distribution within professional switchboards and distribution panels.
The MBT136 is designed for compatible ABB ZH411 or ZH412 NH00 fuse switch-disconnectors, each rated up to 160 A. The module is intended for use with a three-pole 320 A busbar system and provides 24 space units within a compact single-field-width arrangement. Fuse switch-disconnectors and the associated busbar system components are selected separately to suit the completed installation.
With dimensions of 300 × 250 × 200 mm, the MBT136 uses two grid units and one field width. Plastic covers with cut-outs, a RAL 7035 finish and 90-degree press-and-turn fasteners provide a practical finished assembly, while the module can be installed on compatible ABB EDF or WR mounting frames from a cabinet depth of 200 mm.

Reliable Fused Power Distribution for Electrical Assemblies
NH fuse switch-disconnectors combine circuit isolation with fuse-based overcurrent protection, making them widely suited to feeder and distribution circuits in low-voltage electrical assemblies. The ABB MBT136 provides the mechanical module arrangement required to install two compatible NH00 fuse switch-disconnectors within a structured CombiLine panel layout.
The MBT136 supports ABB ZH411 and ZH412 NH00 devices and a three-pole busbar system rated up to 320 A. This modular arrangement enables panel builders to create compact fused distribution sections while retaining convenient integration with compatible ABB mounting frames, busbar components and interior fitting modules.
Typical Applications
- Low-voltage electrical distribution boards.
- Commercial and industrial switchboards.
- NH00 fused feeder circuits.
- Power distribution and circuit isolation sections.
- Main and sub-distribution assemblies.
- Electrical panel building and system integration.
- ABB CombiLine interior expansion systems.
