Why Choose the ABB 1SCA162507R1001 OT100G3-3BS Switch Disconnector?
The ABB 1SCA162507R1001, also known as the OT100G3-3BS, is a compact 100 A, 3-pole switch disconnector from the ABB OT Plus range. Designed for dependable isolation of low-voltage electrical circuits, it is suitable for industrial control panels, distribution boards, machinery and commercial electrical installations.
This front-operated switch disconnector supports both base mounting and 35 mm DIN rail mounting, giving panel builders greater flexibility when designing new assemblies or upgrading existing equipment. Its compact G3 frame is suitable for panels with a 45 mm DIN cut-out, helping maximise available enclosure space without compromising operational safety.
The OT100G3-3BS includes integrated screw terminals and a directly mounted knob handle. The handle can be padlocked in the OFF position to support safe isolation and lockout procedures, while provision for an operating shaft allows the switch to be configured for external door operation using compatible ABB accessories.
Key Advantages
Provides reliable electrical isolation for circuits rated up to 100 A.
Can be converted for external door operation using compatible shafts and handles.

Safe and Flexible Electrical Isolation
The ABB OT100G3-3BS is designed to provide a visible and dependable means of disconnecting electrical equipment from its power supply. This allows maintenance engineers to isolate machinery, distribution circuits and control systems before inspection, servicing or repair work begins.
Its padlockable handle helps prevent unauthorised or accidental reconnection during maintenance. For installations requiring operation from outside an enclosure, a compatible ABB shaft and external handle can be added, allowing the switch body to remain securely mounted inside the panel.
The dual base and DIN rail mounting arrangement makes the 1SCA162507R1001 particularly useful for OEMs and panel builders working across different enclosure formats. Its compact footprint and broad conductor compatibility support efficient integration into power distribution and motor-control systems.
