Why Choose the ABB MT244 NH2 Fuse Switch Expansion 2PW?
The ABB MT244 is a CombiLine NH2 fuse switch disconnector expansion module designed for structured fused power distribution within low-voltage electrical cabinets. Supplied under ABB order code 2CPX041324R9999, the MT244 is a cabinet-mounted 2PW / two-field-width module prepared for the installation of two NH2 fuse switch disconnectors.
The MT244 has a module height of 3 RE / 450 mm, a field width of 2 FB / 500 mm and provides 72 space units. It is supplied unpopulated for two ABB ZH441 NH2 fuse switch disconnectors, each rated up to 400 A, and is designed for a 3-pole busbar system.
The single-level busbar arrangement supports a maximum rated current of 440 A, while the module is suitable for cabinets from 215 mm depth. Plastic covers with equipment cut-outs, 90-degree press-and-turn fasteners and a RAL 7035 finish complete the assembly, with the required EDF or WR mounting frame ordered separately.

Flexible Two-Way NH2 Fused Distribution
The ABB MT244 provides a dedicated CombiLine section for installing two NH2 fuse switch disconnectors within a 3-pole busbar arrangement. Its unpopulated configuration allows ABB ZH441 devices to be selected and installed as required, providing fuse protection and switch-disconnection functionality for two outgoing low-voltage circuits.
With a 500 mm field width, 450 mm module height and 72 space units, the MT244 provides a structured solution for incorporating two NH2 fused ways into a compatible ABB cabinet assembly. The appropriate fuse switch disconnectors, busbar system and EDF or WR mounting frame must be selected separately to complete the installation.
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.
