Why Choose the ABB OS100BS30 Switch Fuse?
The ABB OS100BS30 is a side-operated BS-type switch fuse designed to combine manual circuit isolation with fuse-based protection in industrial low-voltage distribution systems. With ABB order code 1SCA022508R3000, it forms part of the ABB OS switch-fuse range for reliable switching and fuse protection in demanding installations.
Rated at 100 A, the OS100BS30 is a 3-pole unit designed for compatible BS A2 and A3 fuse links. ABB specifies rated operational power values of 55/55/90 kW for AC-23 operation at 415/500/690 V, supporting use in substantial industrial switching applications.
The OS100BS30 is supplied with an OXP6X161 shaft, OHB65J6 black ON-OFF handle and terminal bolt kit as standard. The handle is IP65 protected, padlockable in the OFF position and provides door interlocking in the ON position, while the adjustable shaft supports different enclosure installation depths.

Combined Isolation and Fuse Protection
The ABB OS100BS30 combines a manually operated switching mechanism with compatible BS fuse links, allowing a circuit to be isolated while the installed fuses provide the required overcurrent protection. ABB's OS switch-fuse design isolates the fuse links from both ends when the switch is in the OFF position, supporting safer inspection and maintenance procedures.
The supplied external handle and adjustable shaft enable operation from outside an electrical enclosure. The handle can be padlocked in the OFF position and provides door interlocking in the ON position, making the OS100BS30 well suited to switchboards, machinery and industrial power-distribution assemblies requiring controlled isolation and fuse protection.
Typical Applications
- Industrial low-voltage distribution systems.
- Electrical switchboards and distribution assemblies.
- Three-phase feeder isolation and fuse protection.
- Industrial machinery power supplies.
- Motor and equipment feeder circuits with appropriately selected fuse links.
- Commercial and industrial electrical installations using BS fuse systems.
