Why Choose the ABB OTM40F3CMA230V Motorised Changeover Switch?
The ABB OTM40F3CMA230V is a compact motorised changeover switch designed for reliable transfer between alternative electrical power sources in low-voltage distribution systems. Part of the ABB OT motorised changeover switch range, it provides a 40 A current rating with electrically operated source switching for industrial and commercial applications.
This three-pole switch provides I-0-II open-transition operation, giving two source positions separated by a defined OFF position. Its motor operator enables remote electrical switching, while the supplied handle provides manual operation when local control is required.
With a rated current of 40 A, a 3-pole configuration and a motor operator designed for the 110–240 V AC/DC range, the OTM40F3CMA230V is suitable for mains and standby source selection, generator changeover systems and compact distribution assemblies. Its 40 A AC-31B/AC-33B rating at 415 V supports dependable three-phase power transfer.

Reliable Motorised Power Changeover
Motorised changeover switches allow electrical loads to be transferred between alternative power sources using electrical control rather than requiring routine manual switching at the distribution board. The ABB OTM40F3CMA230V combines motor operation with I-0-II open-transition switching for controlled source selection in three-phase low-voltage systems.
The switch is delivered with a handle for manual operation, a storage clip for the handle and male connectors for the control circuit. Its compact construction and broad motor operating-voltage range make it practical for integration into distribution panels, generator transfer systems and other remotely controlled source-selection assemblies.
Typical Applications
- Main and standby power supply changeover systems.
- Generator and mains supply switching installations.
- Industrial low-voltage distribution boards.
- Commercial building electrical distribution systems.
- Machinery and equipment power-source selection.
- Remote source-selection and transfer systems.
- Three-phase installations requiring compact motorised changeover switching.
