Why Choose the ABB OTM40F4CMA230V Motorised Changeover Switch?
The ABB OTM40F4CMA230V 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 combines a 40 A current rating with four-pole switching and an integrated motor operator.
This switch provides I-0-II open-transition operation, giving two source positions separated by a defined OFF position. The integrated motor drive enables remote electrical source selection, while ABB supplies a handle for manual operation, a handle storage clip and male connectors for the control circuit.
With a rated current of 40 A, a 4-pole configuration and a 110–240 V AC/DC motor operating range, the OTM40F4CMA230V is suited to mains and standby power systems, generator changeover installations and compact distribution assemblies. Its four-pole arrangement simultaneously switches the fourth pole alongside the main poles.

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 OTM40F4CMA230V combines an integrated motor drive with I-0-II open-transition switching, providing controlled source selection while preventing simultaneous connection of the two sources during normal changeover operation.
ABB supplies the switch with a handle for manual operation, a storage clip for the handle and male connectors for the control circuit. Its compact four-pole construction and broad 110–240 V AC/DC motor operating range make it practical for integration into distribution panels, generator transfer systems and 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.
- Four-pole power distribution and source changeover applications.
