Why Choose the ABB OTM315E4CM230C Motorised Changeover Switch?
The ABB OTM315E4CM230C is a heavy-duty 315 A four-pole motorised changeover switch designed for reliable transfer between two electrical power sources. As part of the ABB OT motorised changeover switch range, it combines high-current switching capability with an integrated motor operator for remote source selection in industrial and commercial electrical distribution systems.
The OTM315E4CM230C provides I-0-II open-transition operation, giving defined source I, OFF and source II positions while disconnecting one supply before connecting the alternative source. The switch is supplied with a handle for manual operation, terminal bolt hardware and connectors for its control circuits, providing both motorised and local operating capability.
With a rated current of 315 A, a four-pole configuration and a 220–240 V AC motor operating voltage, the OTM315E4CM230C is suited to mains/generator changeover, standby power systems and alternative supply selection. Its four-pole construction allows four conductors to be switched together in installations requiring this configuration.

Reliable Motorised Power Source Changeover
Motorised changeover switches such as the ABB OTM315E4CM230C provide a controlled method of transferring an electrical load between two independent power sources. Its I-0-II open-transition mechanism provides a defined OFF position between the two connected-source positions, ensuring one supply is disconnected before the alternative supply is selected.
The integrated motor operator enables the OTM315E4CM230C to be controlled remotely as part of a transfer or power-management system, while the supplied manual handle allows local operation when required. This combination makes the switch suitable for demanding installations requiring dependable four-pole power source selection and flexible operating methods.
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.
