ABB OT25F3C 3 pole 25 A manual change-over switch with open transition switching for industrial source transfer, generator change-over and control panel applications.
£91.77
The ABB OT25F3C is a compact and dependable 3-pole manual change-over switch designed for safe power transfer and circuit selection in industrial control panels, machinery and low voltage distribution systems. As part of the trusted ABB OT switch range, it provides reliable manual switching for non-fusible change-over applications.
This front-operated change-over switch is designed for base mounting and provides open transition switching between two supply sources or circuits. Its robust construction, protected terminals and compact footprint make it a practical choice for panel builders, OEMs and electrical engineers.
With a rated current of 25 A and a 3-pole configuration, the OT25F3C is ideal for manual transfer, source selection and change-over duties in industrial and commercial electrical installations. The handle and shaft are ordered separately, allowing the correct operating accessories to be selected for the enclosure.
Change-over switches such as the ABB OT25F3C are used to manually transfer loads between two supply sources or electrical circuits. This makes them suitable for generator change-over, backup supply selection, bypass arrangements and other applications where controlled manual switching is required.
The OT25F3C is particularly suited to industrial panel building where compact size, reliable mechanical operation and flexible external operation are required. Its 3-pole configuration makes it suitable for three-phase manual change-over applications in machinery and electrical distribution systems.

The ABB OT25F3C is used for manual change-over switching between two electrical sources or circuits in industrial panels, machinery and distribution systems.
The OT25F3C is a 3-pole change-over switch, making it suitable for three-phase transfer and source selection applications.
The ABB OT25F3C has a rated current of 25 A.
Open transition means the switch disconnects from one source before connecting to the other, helping prevent the two sources from being connected together during switching.
No, the handle and shaft need to be ordered separately so they can be matched to the enclosure and installation requirements.
ABB OT change-over switches are widely used by panel builders, electrical engineers and OEM machine builders for reliable manual transfer switching, robust operation and flexible integration into industrial electrical systems.
