Flexible NH1 Fused Distribution
The ABB MT142 provides a dedicated CombiLine section for installing one NH1 fuse switch disconnector within a 3-pole busbar arrangement. Its unpopulated design allows the compatible ABB ZH431 fuse switch disconnector to be selected and installed as required, providing fuse protection and switch-disconnection functionality for an outgoing low-voltage circuit.
With a compact 250 mm field width, 450 mm module height and 36 space units, the MT142 provides an efficient way to incorporate NH1 fused distribution into compatible ABB cabinet assemblies. The module is supplied mounted in the cabinet configuration, while the NH1 fuse switch disconnector and appropriate EDF or WR mounting frame must be selected separately.
Typical Applications
- Low-voltage power distribution cabinets.
- ABB CombiLine sub-distribution assemblies.
- NH1 fused outgoing circuit distribution.
- Commercial and industrial switchgear assemblies.
- Fuse-protected feeder and distribution circuits.
- Professional panel-building and electrical installation projects.
