Why Choose the ABB OS315B12LRP Switch Fuse?
The ABB OS315B12LRP, product ID 1SCA022854R8790, is a heavy-duty 315 A three-pole special-connected switch fuse designed for reliable switching, electrical isolation and fuse protection in industrial and commercial low-voltage power distribution systems. As part of the ABB OS Fuse Switches range, it combines dependable load switching with fuse-based overcurrent and short-circuit protection.
The OS315B12LRP features an operating mechanism positioned between the poles together with a specialised left-in/right-out connection arrangement. This configuration supports switchboard and panel designs where the incoming connection is required on the left and the outgoing connection on the right, while maintaining a compact three-pole switching arrangement.
Rated at 315 A, the OS315B12LRP is designed for British Standard BS 88-2 B1–B4 fuse links and supports substantial three-phase loads. ABB specifies operational power ratings of 180 kW, 220 kW and 295 kW across the applicable OS315 operating-voltage range, making this switch fuse well suited to demanding industrial feeders, machinery supplies and power distribution circuits.

Reliable Switching and Fuse Protection
Switch fuses combine manual load switching and electrical isolation with the overcurrent and short-circuit protection provided by correctly selected fuse links. This enables downstream equipment and distribution circuits to be protected while providing a defined means of isolation for operation, servicing and maintenance.
The ABB OS range includes specialised connection arrangements for switchboard designs where conventional top-in/bottom-out connections are not suitable. The OS315B12LRP combines a 315 A three-pole configuration, mechanism between the poles and left-in/right-out connections, providing a purpose-designed solution for installations requiring this particular power-flow arrangement.
Typical Applications
- Industrial low-voltage distribution boards.
- Electrical switchboards and power distribution panels.
- Three-phase feeder isolation and fuse protection.
- Industrial machinery power supplies.
- High-current equipment distribution circuits.
- Panel designs requiring left-in/right-out power connections.
