Why Choose the ABB OS200B03UBP Switch Fuse?
The ABB OS200B03UBP is a robust 200 A 3-pole switch fuse designed for dependable switching, isolation and fuse-based protection in industrial low-voltage electrical systems. As part of the ABB OS fuse switch series, it is engineered for professional power distribution and machinery applications requiring reliable three-phase circuit isolation.
This exact OS200B03UBP configuration features a top-in, back-out (UB) terminal arrangement, allowing incoming conductors to connect at the top while outgoing connections are routed from the rear. It uses British Standard B1–B2 fuse sizes and provides a purpose-designed connection layout for installations where rear outgoing cabling is advantageous.
With a rated current of 200 A and a 3-pole configuration, the OS200B03UBP is suitable for three-phase feeders, switchboards, machinery and industrial distribution systems. It is supplied with an operating handle, shaft and terminal bolt kits, providing the principal operating components required for enclosure installation.

Reliable Switching and Fuse Protection
Switch fuses combine manual circuit switching and isolation with fuse-based overcurrent and short-circuit protection. This arrangement allows downstream equipment to be disconnected while appropriately selected fuse links protect the electrical circuit against fault conditions.
The ABB OS200B03UBP provides this functionality in a 200 A three-pole configuration with a specialised top-in, back-out connection arrangement. Its British Standard fuse compatibility, included operating components and flexible terminal layout make it particularly suitable for industrial switchboards and electrical panels where rear outgoing connections simplify cable routing.
Typical Applications
- Industrial low-voltage power distribution systems.
- Three-phase feeder and distribution circuits.
- Electrical switchboards with rear outgoing connections.
- Machinery isolation and protection circuits.
- Industrial control cabinets and electrical enclosures.
- Commercial and infrastructure electrical installations.
