Why Choose the ABB OSM100GB4N1M230C Motorised Switch Fuse?
The ABB OSM100GB4N1M230C is a 100 A four-pole motorised switch fuse designed for remote switching, isolation and fuse-protected low-voltage power distribution. Identified by ABB order code 1SCA118779R1001, it belongs to ABB's OSM range of motor-operated switch fuses for applications requiring reliable electrical operation with provision for manual operation.
This model combines motorised switching with British Standard fuse protection in a compact assembly. It is rated for AC-20 to AC-23 utilisation up to 690 V and accepts A2–A4 fuse sizes, making it suitable for industrial distribution systems where remote operation and effective fuse protection are required.
The OSM100GB4N1M230C has a four-pole configuration incorporating an N1 non-fused switched neutral on the left side. Its motor operating voltage is 220–240 V AC, while a handle for manual operation, control-circuit connectors and terminal bolt hardware are included to support installation and commissioning.

Remote-Controlled Fused Switching and Isolation
Motorised switch fuses provide the switching, isolation and fuse-protection functions of a conventional switch fuse while adding electrical operation for remote-control applications. ABB's OSM design also supports manual operation, providing an alternative means of operating the switch when required during installation, commissioning or maintenance.
With its 100 A rating, four-pole arrangement, A2–A4 fuse compatibility and 220–240 V AC motor drive, the OSM100GB4N1M230C is designed for automated and remotely controlled low-voltage distribution systems requiring dependable fused isolation.
Typical Applications
- Remotely operated low-voltage switchboards.
- Automated electrical distribution systems.
- Industrial power distribution panels.
- Three-phase and neutral feeder circuits.
- Motor control centres and machinery distribution.
- Building and industrial power-management systems.
