Why Choose the ABB OTM400E4CM230C Motorised Changeover Switch?
The ABB OTM400E4CM230C is a heavy-duty 400 A four-pole motorised changeover switch designed for controlled transfer between two electrical power sources. As part of the ABB OT motorised changeover switch range, it combines robust high-current switching with an integrated motor operator for remote source selection in industrial, commercial and infrastructure power distribution systems.
The OTM400E4CM230C provides I-0-II open-transition operation, giving clearly defined source I, OFF and source II positions. Its open-transition mechanism disconnects one source before connecting the alternative source, while the integrated motor operator enables remote electrical operation and the supplied direct-mounted handle provides manual operation when required.
With a rated current of 400 A, a four-pole configuration and a 220–240 V AC motor operating voltage, the OTM400E4CM230C is suitable for mains/generator transfer, standby power systems and alternative supply selection. Its four-pole construction enables four conductors to be switched together, while its 275 kVA rating at 400 V supports demanding power-distribution applications.

Reliable Motorised Power Source Changeover
Motorised changeover switches such as the ABB OTM400E4CM230C provide a controlled method of transferring electrical loads between two independent power sources. The I-0-II open-transition arrangement provides a defined disconnected position between source I and source II, ensuring one supply is disconnected before the alternative supply is connected.
The integrated 220–240 V AC motor operator enables remote operation from an appropriate transfer-control or power-management system. A direct-mounted manual handle provides local operating capability, making the OTM400E4CM230C suitable for installations requiring dependable four-pole source selection with both motorised and manual control.
Typical Applications
- Mains and generator power source changeover systems.
- Standby and emergency power distribution.
- Industrial electrical switchboards.
- Commercial building power distribution systems.
- Alternative supply selection systems.
- Four-pole power transfer installations requiring remote motorised operation.
