Why Choose the ABB OS200B21LRP Switch Fuse?
The ABB OS200B21LRP is a robust 200 A 3-pole switch fuse designed for reliable switching, isolation and fuse protection in industrial low-voltage electrical systems. Identified by ABB order code 1SCA022854R3050, this model belongs to the ABB OS switch fuse series and is designed for BS-type fuse links.
This specific OS200B21LRP configuration uses the B21 arrangement with a left-in, right-out (LR) connection. The specialised connection layout supports efficient integration into industrial switchboards and distribution assemblies where defined incoming and outgoing conductor positions are required.
With a rated operational current of 200 A, a 3-pole configuration and compatibility with B1–B2 fuse sizes, the OS200B21LRP provides dependable fused isolation for three-phase circuits. It is front operated and supplied with a black operating handle, adjustable shaft and terminal bolt kit for practical panel installation.

Reliable Fused Isolation for Industrial Distribution
Switch fuses combine load switching and circuit isolation with fuse-based protection. Correctly selected fuse links provide protection against overload and short-circuit conditions, while the manually operated switch enables the associated circuit to be disconnected and isolated for operation or maintenance.
The ABB OS200B21LRP is specifically configured with left-in, right-out connections, making it suitable for switchgear layouts where conductor routing and equipment arrangement are important. Its front-operated construction and included handle and shaft support straightforward integration into industrial electrical panels.
Typical Applications
- Industrial low-voltage distribution boards.
- Three-phase electrical distribution systems.
- Switchgear and switchboard assemblies.
- Machine and equipment power isolation.
- Fused feeder and distribution circuits.
- OEM machinery and industrial control systems.
