Why Choose the ABB OS63GB22N1 Switch Fuse?
The ABB OS63GB22N1 is a 63 A 4-pole front-operated 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 base-mounted assembly.
This configuration uses the 22 operating mechanism positioned between the poles and accepts British Standard A2–A3 fuse sizes. Its fourth pole is switched with a solid link, providing coordinated four-pole switching while the fused poles accommodate the appropriate fuse links for circuit protection.
The OS63GB22N1 is rated at 63 A with a rated operational voltage of 690 V AC. It features screw terminals and base mounting and is supplied without a handle and shaft, allowing suitable operating accessories to be selected separately for the required panel or switchboard arrangement.

Reliable Switching, Isolation 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 OS63GB22N1 provides a 63 A four-pole solution using British Standard A2–A3 fuse links. Its front-operated mechanism between the poles, switched solid-link fourth pole, base mounting and screw terminals make it suitable for integration into 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.
