Why Choose the ABB OTM315E3CM230C Motorised Changeover Switch?
The ABB OTM315E3CM230C is a heavy-duty motorised changeover switch designed for reliable transfer between alternative electrical power sources in industrial and commercial low-voltage distribution systems. Part of the ABB OT motorised changeover switch range, it combines a 315 A current rating with electrically operated source switching for demanding three-phase applications.
This three-pole switch provides I-0-II open-transition operation, with two source positions separated by a defined OFF position. Its integrated motor operator enables remote electrical switching, while the included handle provides manual operating capability when local control is required.
With a rated current of 315 A, a 3-pole configuration and a 220–240 V AC motor operating voltage, the OTM315E3CM230C is suitable for mains and standby power systems, generator changeover installations and industrial distribution switchboards. Its 215 kVA rating at 400 V provides substantial switching capacity for three-phase power distribution.

Reliable Motorised Power Changeover
Motorised changeover switches allow electrical loads to be transferred between alternative power sources through remote electrical control. The ABB OTM315E3CM230C uses an I-0-II open-transition arrangement, disconnecting the active source before the alternative source is connected and providing a defined OFF position between the two supplies.
The integrated motor mechanism supports remote source selection, while the supplied manual operating handle provides local operation when required. ABB also supplies terminal bolt hardware and male connectors for the control circuits, supporting practical integration into switchboards and power transfer assemblies.
Typical Applications
- Main and standby power supply changeover systems.
- Generator and mains supply switching installations.
- Industrial low-voltage distribution switchboards.
- Commercial building electrical distribution systems.
- Manufacturing and process plant power systems.
- Remote source-selection and transfer systems.
- Three-phase power distribution installations.
