Why Choose the ABB OS630B22N2P Switch Fuse?
The ABB OS630B22N2P is a heavy-duty 630 A four-pole BS88 switch fuse designed for reliable switching, isolation and fuse-protected power distribution in demanding low-voltage electrical installations. Identified by ABB order code 1SCA022825R6660, this model forms part of the ABB OS fuse switch series and is designed for British Standard C1–C2 fuse sizes.
The OS630B22N2P combines manual switching and isolation with fuse protection in a robust assembly for high-current distribution systems. Its four-pole configuration incorporates a non-fused switched neutral on the right side, enabling simultaneous switching of the neutral conductor in suitable three-phase electrical installations.
Rated at 630 A, this configuration uses an operating mechanism positioned between the poles and is supplied with the appropriate handle and shaft. Its base-mounted construction makes it well suited to integration into industrial switchboards, distribution panels and other high-current electrical assemblies.

Reliable High-Current Fused Switching
Switch fuses combine load switching and electrical isolation with fuse-based overcurrent protection. This provides a practical solution for high-current feeders and distribution circuits where both a defined means of isolation and correctly selected fuse protection are required.
The ABB OS range is engineered for integration into low-voltage switchboards and power distribution systems. With its 630 A rating, four-pole configuration, BS88 C1–C2 fuse compatibility and switched neutral arrangement, the OS630B22N2P provides a robust solution for demanding industrial electrical installations.
Typical Applications
- Industrial low-voltage switchboards.
- Main and sub-distribution panels.
- High-current three-phase distribution systems.
- Circuits requiring switched neutral functionality.
