Why Choose the ABB OT40F3C Change-Over Switch?

The ABB OT40F3C 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 supports manual 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 operational current of 40 A and a 3-pole configuration, the OT40F3C is ideal for manual transfer, source selection and change-over duties in industrial and commercial electrical installations. The handle and shaft need to be ordered separately, allowing the correct operating accessories to be selected for the enclosure.
