Why Choose the ABB OTM400E4CM110V Motorised Changeover Switch?
The ABB OTM400E4CM110V 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 switching performance with an integrated motor operator for remote source selection in industrial, commercial and infrastructure power distribution systems.
The OTM400E4CM110V provides open-transition changeover operation, disconnecting one source before the alternative source is connected. Its integrated motor operator enables remote electrical switching, while the direct-mounted manual handle provides local operating capability for commissioning, maintenance and other operational requirements.
With a rated current of 400 A, a four-pole configuration and a motor operating voltage of 110–125 V AC/DC, the OTM400E4CM110V is suitable for mains/generator changeover, standby power systems and alternative supply selection. The switch provides an AC-23A operational power rating of 220 kW at 380–415 V and is designed for base mounting within electrical distribution assemblies.

Reliable Motorised Power Source Changeover
Motorised changeover switches such as the ABB OTM400E4CM110V provide a controlled method of transferring electrical loads between two independent power sources. Its open-transition switching arrangement disconnects the active source before connecting the alternative supply, maintaining separation between the two sources during the changeover process.
The integrated motor operator allows the OTM400E4CM110V to be controlled remotely as part of an appropriate transfer-control or power-management system. Its four-pole construction, manual operating handle and high-current switching capability make it suitable for demanding installations requiring reliable source selection and flexible local or remote operation.
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.
