Why Choose the ABB 1SCA022845R3650 OS250D22N2-60 Switch Fuse?
The ABB 1SCA022845R3650, order code OS250D22N2-60, is a 250 A, 4-pole switch fuse designed for reliable switching, isolation and fuse-protected power distribution in industrial low-voltage installations. As part of the ABB 311027-OT Switches product group, it combines load switching and isolation with DIN-type fuse protection in a robust switch-fuse assembly.
The OS250D22N2-60 features a right-side non-fused fourth pole, providing four-pole switching while the three main phase poles accommodate fuse links. ABB identifies the N2 configuration as a four-pole switch with the fourth pole positioned on the right side, making this arrangement suitable for applications requiring simultaneous switching of an additional conductor without fuse protection on that pole.
With a rated current of 250 A and compatibility with DIN 01 fuse links, the OS250D22N2-60 is engineered for demanding industrial distribution, machinery and switchboard applications. Its front-operated design provides straightforward manual control, while the OS switch-fuse platform delivers dependable isolation and fuse-based short-circuit protection when correctly selected fuse links are installed.

Reliable Switching and Fuse Protection for Power Distribution
Switch fuses combine a load-switching and isolation mechanism with replaceable fuse links, allowing a circuit to be manually disconnected while providing fuse-based protection against overcurrents and short circuits. The ABB OS250D22N2-60 is designed around this principle for higher-current industrial distribution systems where dependable isolation and coordinated fuse protection are required.
The four-pole configuration allows an additional conductor to be switched together with the three phase conductors. On the OS250D22N2-60, this fourth pole is positioned on the right side and is non-fused, while the main fused poles accept DIN 01 fuse links. This arrangement is particularly useful in distribution systems requiring four-pole isolation without a fuse in the fourth switched conductor.
Typical Applications
- Industrial low-voltage power distribution.
- Main and sub-distribution switchboards.
- Machinery and production equipment isolation.
- Motor and industrial load feeder circuits.
- Electrical distribution panels.
- Commercial and industrial building services.
- Fuse-protected feeder and isolation applications.
