Why Choose the ABB OS63GB22N1P Switch Fuse?
The ABB OS63GB22N1P is a 63 A 4-pole switch fuse designed for reliable switching, isolation and fuse protection in low-voltage electrical distribution systems. Part of the ABB OS fuse switch range, it combines manual circuit isolation with British Standard fuse protection in a compact assembly for industrial and commercial applications.
This configuration uses the 22 operating mechanism positioned between the poles and accommodates British Standard A2–A3 fuse sizes. The fourth pole is positioned on the left and uses a non-fused switched solid link, providing coordinated four-pole switching while the fused poles accommodate the appropriate fuse links.
The OS63GB22N1P is rated at 63 A and supports operational currents of 63 A at up to 690 V AC for AC-21A, AC-22A and AC-23A utilisation categories. This version is supplied with a pistol handle and shaft, providing a complete front-operated arrangement for integration into electrical panels and switchboards.

Reliable Four-Pole Switching and Fuse Protection
Switch fuses combine manual circuit isolation with fuse-based overcurrent protection. This arrangement enables electrical circuits to be positively disconnected for operation or maintenance while correctly selected fuse links provide protection against potentially damaging overcurrent and short-circuit conditions.
The ABB OS63GB22N1P provides a 63 A four-pole solution using British Standard A2–A3 fuse links. Its mechanism between the poles, switched solid-link fourth pole and included pistol handle and shaft provide a practical configuration for industrial control panels, switchboards and low-voltage distribution assemblies.
Typical Applications
- Industrial low-voltage distribution systems.
- Electrical switchboards and distribution panels.
- Four-pole feeder and isolation circuits.
- Industrial machinery and control panels.
- Fuse-protected power distribution circuits.
- OEM switchgear and electrical assemblies.
