Why Choose the ABB OS160GB03-42 160 A 3-Pole BS Switch Fuse?
The ABB OS160GB03-42 is a robust 160 A 3-pole switch fuse designed for switching, isolation and fuse-based protection in low-voltage electrical distribution systems. Part of the ABB OS160 Gamma range, it combines dependable manual isolation with British Standard fuse protection for industrial and commercial applications.
The OS160GB03-42 uses the British Standard fuse system and accommodates A2–A4 fuse links with a maximum fuse diameter of 32 mm. The -42 configuration incorporates integrated nuts on the terminals, together with a terminal bolt set, to support straightforward installation within electrical panels and switchboards.
Rated at 160 A with a 3-pole configuration, the OS160GB03-42 is front operated with its 03 operating mechanism located on the left side. This version is supplied without a handle and operating shaft, allowing compatible ABB operating accessories to be selected separately to suit the enclosure and installation arrangement.

Reliable 160 A Switching, Isolation and Fuse Protection
The ABB OS160GB03-42 combines manual circuit switching and isolation with the protection provided by appropriately selected British Standard A2–A4 fuse links. Its 160 A, 3-pole configuration enables all three phases of a three-phase circuit to be switched together while the installed fuses provide overcurrent and short-circuit protection according to their selected characteristics.
The -42 integrated-nut terminal arrangement is designed to simplify connection during switchboard assembly, while the front-operated mechanism is positioned on the left side of the switch. As the handle and shaft are not included, suitable ABB operating accessories can be selected to match the enclosure depth and required external operating arrangement.
Typical Applications
- Industrial three-phase power distribution systems.
- Main and sub-distribution switchboards.
- Three-phase feeder switching and isolation.
- Industrial machinery and equipment supplies.
- Electrical control panels and distribution assemblies.
- Installations requiring British Standard A2–A4 fuse protection.
