Flexible NH2 Fused Distribution
The ABB MT144 provides a dedicated CombiLine section for installing one NH2 fuse switch disconnector within a 3-pole busbar system. Its unpopulated design allows the compatible ABB ZH441 to be installed for the application, providing fuse protection and switch-disconnection functionality for a high-current outgoing low-voltage circuit.
With a compact 250 mm field width, 450 mm module height and 36 space units, the MT144 provides an efficient way to incorporate an NH2 fused outgoing way into a compatible ABB cabinet assembly. The module is supplied mounted for cabinet installation, while the NH2 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.
- NH2 fused outgoing circuit distribution.
- Commercial and industrial switchgear assemblies.
- High-current fuse-protected feeder circuits.
- Professional panel-building and electrical installation projects.
