Why Choose the ABB MT136 NH00 Fuse Switch Expansion?
The ABB MT136 is a factory-assembled CombiLine N NH00 fuse switch-disconnector expansion module designed for compatible ABB sub-distribution cabinets. Supplied under ABB order code 2CPX041299R9999, it forms part of the ABB DESUJ Sub Distribution product group and provides a 1 PW / 250 mm field width.
The MT136 has a 2 RE / 300 mm module height, provides 24 space units and is configured for two NH00 fuse switch-disconnectors. The assembled module is designed for ABB ZH411 or ZH412 NH00 devices rated up to 160 A and incorporates a 3-pole 320 A busbar system.
Designed for professional low-voltage power distribution, the MT136 combines compact fuse-switch installation capacity with a structured busbar arrangement. It is suitable for cabinets from 200 mm deep and can be used with compatible EDF or WR mounting frames, which are ordered separately.

Compact NH00 Fuse-Switch Distribution
The ABB MT136 provides a structured installation platform for two NH00 fuse switch-disconnectors within a compact 250 mm field width. Its 3-pole busbar system is rated up to 320 A, allowing the module to integrate fused outgoing circuits into compatible CombiLine N sub-distribution assemblies.
NH00 fuse switch-disconnectors combine circuit isolation with fuse-based overcurrent protection in a compact format. By integrating two NH00 positions and the associated busbar system into a factory-assembled module, the MT136 supports efficient and orderly construction of professional low-voltage distribution boards.
Typical Applications
- Electrical sub-distribution boards.
- ABB CombiLine N distribution systems.
- NH00 fused outgoing circuits.
- Commercial building power distribution.
- Industrial low-voltage distribution panels.
- Distribution-board extensions requiring compact fused feeders.
