Why Choose the ABB OTM400E3CM230C Motorised Changeover Switch?
The ABB OTM400E3CM230C 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 400 A current rating with electrically operated source switching for demanding three-phase applications.
This three-pole switch provides I-0-II open-transition operation, giving 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 400 A, a 3-pole configuration and a 220–240 V AC motor operating voltage, the OTM400E3CM230C is suitable for mains and standby power systems, generator changeover installations and industrial distribution switchboards. Its 275 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 OTM400E3CM230C 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 OTM400E3CM230C is delivered with a handle for manual operation, a bolt kit with nuts and washers for all terminals and male connectors for the control circuits. A storage clip for the operating handle and spare fuses are also included, supporting practical installation and maintenance within power distribution 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.
