Why Choose the ABB OT25F4C Change-Over Switch?
The ABB OT25F4C is a compact and dependable 4-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 DIN rail mounting, providing flexible installation for panel builders, OEMs and electrical engineers. Its robust construction, protected terminals and compact footprint make it a practical choice for industrial and commercial electrical panels.
With a rated current of 25 A and a 4-pole configuration, the OT25F4C is ideal for manual transfer, source selection and change-over duties where three-phase plus neutral switching is required. The handle and shaft are ordered separately, allowing the correct operating accessories to be selected for the enclosure.
