Why Choose the ABB OS100GB22N1-42 100 A 4-Pole BS Switch Fuse?
The ABB OS100GB22N1-42 is a 100 A, 4-pole, front-operated switch fuse designed for switching, isolation and fuse protection in low-voltage electrical distribution systems. Part of the ABB OS range, this GB-type model uses the British Standard fuse system and is designed for A2-A4 fuse links.
This -42 version features integrated nuts on the back of the terminals, helping simplify installation and terminal connection. The OS100GB22N1-42 also incorporates a non-fused switched neutral on the left side, providing a four-pole arrangement for applications requiring simultaneous phase and neutral switching.
Rated at 100 A, the OS100GB22N1-42 is supplied without an operating handle or shaft, allowing suitable ABB operating accessories to be selected separately for the enclosure and installation depth. Its front-operated, base-mounted construction makes it well suited to industrial switchboards and distribution assemblies.
Key Advantages
- 100 A, 4-pole switch fuse for industrial low-voltage distribution.

Four-Pole Fused Switching with Integrated Backnuts
The ABB OS100GB22N1-42 combines manual switching and isolation with fuse-based circuit protection in a four-pole arrangement. Its N1 non-fused switched neutral is positioned on the left side, enabling neutral switching alongside the fused phase conductors in applications requiring coordinated phase and neutral isolation.
The -42 terminal design incorporates nuts on the back of the terminals to simplify assembly and connection within switchgear. Because the operating handle and shaft are not included, appropriate ABB accessories can be selected separately to suit the enclosure depth and required operating arrangement.
Typical Applications
- Industrial low-voltage power distribution.
- Four-pole electrical isolation systems.
- Switchboards and distribution panels.
- British Standard fused distribution circuits.
- Three-phase systems requiring switched neutral isolation.
- Industrial machinery and equipment feeders.
