2CPX041320R9999 ABB MT145B NH2 Fuse Switch Expansion Module 1PW

Why Choose the ABB MT145B NH2 Fuse Switch Expansion Module?

The ABB MT145B, order code 2CPX041320R9999, is a mounted and equipped NH2 fuse switch disconnector expansion module designed for ABB CombiLine electrical distribution systems. Part of ABB’s DESUJ Sub Distribution product group, it provides a ready-equipped solution for integrating NH2 fused switching and isolation into commercial and industrial sub-distribution cabinets.

The MT145B is equipped with two ABB NH2 fuse switch disconnectors and incorporates a 3-pole busbar system. The fitted NH2 devices are designed for currents up to 400 A, while the module’s double-storey busbar configuration supports a maximum rated current of 630 A, making it suitable for demanding power distribution applications.

With a module height of 5 RE / 750 mm, a panel width of 1 PW / 250 mm and 60 space units, the MT145B provides two NH2 disconnector positions within a compact single-panel-width format. The module is suitable for cabinets from 215 mm depth and can be installed on compatible ABB EDF or WR mounting frames, which must be ordered separately.

Reliable NH2 Fused Power Distribution

NH2 fuse switch disconnectors combine fuse protection with switching and isolation functions for higher-current electrical distribution circuits. The ABB MT145B provides two integrated NH2 disconnector positions together with the associated 3-pole busbar infrastructure, helping panel builders create organised, protected and serviceable fused outgoing circuits within CombiLine distribution assemblies.

The MT145B is supplied equipped with two NH2 fuse switch disconnectors, reducing the component selection and assembly required during panel construction. Its 630 A double-storey busbar configuration, compact 250 mm panel width and compatibility with both EDF and WR mounting frames make it a practical solution for higher-current distribution where cabinet width is limited.

Typical Applications

• Commercial and industrial sub-distribution boards.
• ABB CombiLine electrical cabinet assemblies.
• NH2 fused outgoing circuits.
• Higher-current electrical power distribution systems.
• Industrial switchgear and control cabinets.
• Panel building and modular power distribution installations.
