Why Choose the ABB OS800B22N2P Switch Fuse?
The ABB OS800B22N2P is a heavy-duty 800 A four-pole British Standard switch fuse designed for dependable switching, isolation and fuse-protected low-voltage power distribution. Identified by ABB order code 1SCA022825R8440, this model forms part of the ABB OS fuse switch series and is designed for BS88 C1–C3 fuse links.
The OS800B22N2P combines high-current switching and electrical isolation with fuse protection in a robust assembly. Its configuration provides three fused poles plus an N2 non-fused switched neutral on the right side, making it suitable for three-phase systems where the neutral conductor must also be switched.
Rated at 800 A, the OS800B22N2P uses British Standard C1–C3 fuses and has its operating mechanism between the poles. This P-version is supplied with an OHB145J12 operating handle, OXP12X280 shaft and M12 × 40 terminal bolts for integration into suitable switchboard installations.

Reliable High-Current Fused Switching
Switch fuses combine load switching and electrical isolation with fuse-based overcurrent protection, providing a robust solution for high-current feeders and distribution circuits. The use of appropriately selected BS88 fuse links enables effective circuit protection while the switch mechanism provides a defined means of manual isolation.
The ABB OS range is engineered for demanding low-voltage power distribution. With its 800 A rating, BS88 C1–C3 fuse compatibility and N2 switched neutral, the OS800B22N2P is particularly suited to high-current three-phase and neutral distribution systems requiring coordinated fused switching and isolation.
Typical Applications
- Industrial low-voltage switchboards.
- Main electrical distribution panels.
- High-current three-phase and neutral feeders.
- Industrial machinery power distribution.
- Motor control centres and distribution assemblies.
- Fuse-protected switching and isolation applications.
