Why Choose the ABB OS160GB12BBP 160 A 3-Pole BS Switch Fuse?
The ABB OS160GB12BBP is a heavy-duty 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 provides dependable fused isolation for industrial switchboards, machinery panels and commercial power-distribution assemblies.
A defining feature of the OS160GB12BBP is its back-in, back-out connection arrangement, allowing both incoming and outgoing conductors to connect from the rear of the switch fuse. It uses the British Standard BS 88-2 fuse system and accommodates A2–A4 fuse links with a maximum fuse body diameter of 32 mm.
Rated at 160 A with a 3-pole configuration, the OS160GB12BBP is front operated with its mechanism positioned between the poles. This P version includes a 161 mm OXP6X161 operating shaft, OHB65J6 external handle and M8 × 25 terminal bolts, providing the principal operating components required for installation in a suitable enclosure.

Back-In, Back-Out Switching and Fuse Protection
The ABB OS160GB12BBP 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 fuse links provide overcurrent and short-circuit protection according to their selected characteristics.
The specialised back-in, back-out connection arrangement enables both sides of the main circuit to be connected from the rear, making the OS160GB12BBP particularly useful for switchboard layouts where rear cabling is preferred. The mechanism sits between the poles, while the supplied OHB65J6 handle and 161 mm OXP6X161 shaft provide an external front-operating arrangement for enclosure installation.
Typical Applications
- Industrial three-phase power distribution systems.
- Rear-connected low-voltage switchboards.
- Main and sub-distribution panels.
- Three-phase feeder switching and isolation.
- Industrial machinery and equipment supplies.
- Installations requiring British Standard fuse protection with back-in, back-out connections.
