Why Choose the ABB OS100GB12 Switch Fuse?
The ABB OS100GB12 is a 100 A, 3-pole switch fuse mechanism designed to combine manual circuit switching and isolation with fuse-based protection in industrial low-voltage distribution systems. With ABB order code 1SCA116969R1001, it forms part of the ABB OS switch-fuse range.
The OS100GB12 is a front-operated, GB-type switch fuse designed for compatible British Standard fuse links. Its 3-pole configuration is suitable for three-phase circuits, providing simultaneous switching of all three poles through a common operating mechanism.
This version is supplied as the switch-fuse mechanism without handle and shaft, allowing the appropriate operating accessories to be selected separately to suit the enclosure and installation arrangement. This makes the OS100GB12 particularly useful for panel builders and switchboard manufacturers requiring flexibility when configuring the external operating system.
Key Advantages
- 100 A rated current for industrial low-voltage switching applications.
- 3-pole configuration for three-phase circuit switching and isolation.
- Combines manual isolation with fuse-based circuit protection.
- Front-operated mechanism suitable for switchboard and enclosure installations.
- Designed for compatible GB-type fuse links.
- Supplied without handle and shaft, allowing operating accessories to be selected for the installation.
- Part of ABB's established OS switch-fuse range.
Key Features
- ABB OS100 series switch fuse.
- 100 A rated current.
- 3 poles.
- GB-type fuse system.
- Front-operated configuration.
- Designed for compatible A2–A4 fuse sizes.
- Switch-fuse mechanism supplied without external handle.
- Shaft not included.
- Suitable for base-mounted switchgear installations.
- ABB order code 1SCA116969R1001.
Flexible Three-Phase Switching and Fuse Protection
The ABB OS100GB12 combines a 3-pole switching mechanism with provision for compatible fuse links, enabling three-phase circuits to be manually switched and isolated while the installed fuses provide the appropriate overcurrent protection. This integrated approach makes OS switch fuses suitable for feeder, machinery and distribution applications where both isolation and fuse protection are required.
Because the OS100GB12 is supplied without a handle and shaft, these operating components can be selected separately according to the required enclosure depth and operating arrangement. This provides installation flexibility for panel builders and system integrators while retaining the purpose-designed ABB OS switch-fuse mechanism.
Typical Applications
- Industrial low-voltage distribution systems.
- Three-phase feeder switching and fuse protection.
- Electrical switchboards and distribution panels.
- Industrial machinery power supplies.
- Panel-building and OEM switchgear assemblies.
- Equipment isolation and maintenance switching.
