Why Choose the ABB OTM2000E3CM230C Motorised Changeover Switch?
The ABB OTM2000E3CM230C is a heavy-duty motorised changeover switch designed for reliable transfer between two electrical power sources in high-current industrial and commercial power distribution systems. As part of the ABB OT motorised changeover switch range, it combines a substantial 2000 A current rating with electrically operated source changeover for demanding low-voltage installations.
This three-pole changeover switch uses an open-transition I-0-II switching arrangement and incorporates a motorised operating mechanism for remote electrical control. It is supplied with a handle for manual operation, terminal bolt hardware and connectors for the control circuits, providing a practical solution for integration into large switchboards and power transfer assemblies.
With a rated current of 2000 A, a 3-pole configuration and a 220–240 V AC motor operating voltage centred on 230 V AC, the OTM2000E3CM230C is engineered for substantial mains, generator and alternative supply changeover duties. Its robust electrical ratings and base-mounted construction support dependable operation in demanding power distribution environments.

Reliable Motorised Power Changeover
Motorised changeover switches allow electrical loads to be transferred between alternative power sources through remote control rather than requiring routine manual operation at the switchboard. The ABB OTM2000E3CM230C provides open-transition switching, disconnecting the active source before the alternative source is connected.
Its three-pole construction is designed for three-phase power systems, while the motorised operating mechanism supports integration with external transfer control equipment. The switch is supplied with a manual operating handle, an M12 × 60 mm terminal bolt kit with nuts and washers, and male connectors for the control circuits.
Typical Applications
- Main and standby power supply changeover systems.
- Generator and mains supply switching installations.
- Industrial low-voltage distribution switchboards.
- Commercial building power distribution systems.
- Manufacturing and process plant electrical systems.
- Infrastructure and critical power distribution installations.
- High-current three-phase source transfer systems.
