Reliable Switching and Fuse Protection
Switch fuses combine manual circuit switching and isolation with fuse-based overcurrent and short-circuit protection. This enables downstream electrical equipment to be disconnected while correctly selected fuse links provide protection against electrical fault conditions, making switch fuses well suited to industrial distribution and machinery applications.
The ABB OS200GB03-42 provides this functionality in a 200 A three-pole British Standard configuration. Its integrated back nuts and supplied terminal bolt set simplify electrical connection, while the separate handle and shaft arrangement enables panel builders to select compatible operating accessories appropriate to the enclosure design.
Typical Applications
- Industrial low-voltage power distribution systems.
- Three-phase feeder and distribution circuits.
- Electrical switchboards and distribution panels.
- Machinery isolation and fuse protection.
- Industrial control cabinets and electrical enclosures.
- OEM and panel-building applications requiring integrated terminal nuts.
