Why Choose the ABB OTM315E4CM24D Motorised Changeover Switch?
The ABB OTM315E4CM24D is a robust 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, commercial and infrastructure power distribution systems.
The OTM315E4CM24D provides I-0-II open-transition operation, giving defined source I, OFF and source II positions while ensuring one source is disconnected before the alternative source is connected. It is supplied with a handle for manual operation, terminal bolt hardware and control-circuit connectors, providing a practical solution for both remotely controlled and locally operated source-transfer systems.
With a rated current of 315 A, a four-pole configuration and a 24 V DC motor operating voltage, the OTM315E4CM24D is suitable for mains/generator transfer, standby power systems and alternative supply selection. Its four-pole arrangement allows all four conductors to be switched as part of the changeover process.

Reliable Motorised Power Source Changeover
Motorised changeover switches such as the ABB OTM315E4CM24D provide a controlled method of transferring electrical loads between two independent power sources. The I-0-II open-transition arrangement provides an intermediate disconnected position, ensuring the active source is disconnected before the alternative source is connected.
The integrated 24 V DC motor operator enables remote operation from a suitable transfer-control or power-management system, while the direct-mounted manual handle provides local operating capability. This combination makes the OTM315E4CM24D suitable for installations requiring dependable four-pole source selection with both electrical 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.
