Why Choose the ABB OS250B22PRN2P Switch Fuse?
The ABB OS250B22PRN2P is a robust 250 A 4-pole switch fuse designed for dependable switching, isolation and fuse-based protection in industrial low-voltage electrical systems. Part of the ABB OS fuse switch series, it provides a purpose-designed solution for power distribution, machinery and switchboard applications requiring reliable circuit isolation.
This exact OS250B22PRN2P configuration is a plug-in switch fuse mechanism module with a right-out connection arrangement and N2 configuration. Its four-pole construction makes it suitable for installations requiring four-pole switching, while the specialised plug-in design supports integration into compatible switchboard assemblies.
With a rated current of 250 A, the OS250B22PRN2P uses the British Standard fuse-switch platform and is designed for B1–B3 fuse sizes. The plug-in, right-out arrangement provides a practical configuration for electrical assemblies where the specified right-side outgoing connection is required.

Reliable Switching and Fuse Protection
Switch fuses combine manual circuit switching and isolation with fuse-based overcurrent and short-circuit protection. Correctly selected fuse links provide protection against electrical fault conditions while the switching mechanism enables downstream equipment to be isolated for operation, servicing or maintenance.
The ABB OS250B22PRN2P provides this functionality in a 250 A four-pole configuration with its operating mechanism between the poles. Its plug-in, right-out arrangement and N2 configuration make it particularly suitable for professional switchboards and electrical distribution assemblies requiring this specific connection layout.
Typical Applications
- Industrial low-voltage power distribution systems.
- Four-pole feeder and distribution circuits.
- Electrical switchboards and distribution panels.
- Machinery isolation and fuse protection.
- Industrial control cabinets and electrical assemblies.
- Installations requiring plug-in, right-out connections.
