Why Choose the ABB OTM315E3CM24D Motorised Changeover Switch?
The ABB OTM315E3CM24D is a heavy-duty motorised changeover switch designed for reliable transfer between alternative electrical power sources in industrial and commercial low-voltage distribution systems. Part of the ABB OT motorised changeover switch range, it combines a 315 A current rating with electrically operated source switching for demanding three-phase applications.
This three-pole switch provides I-0-II open-transition operation, with two source positions separated by a defined OFF position. Its integrated motor operator enables remote electrical switching, while manual operation provides a practical local switching option for installation and maintenance requirements.
With a rated current of 315 A, a 3-pole configuration and a 24 V DC motor operating voltage, the OTM315E3CM24D is suitable for mains and standby power systems, generator changeover installations and industrial distribution switchboards. Its 215 kVA rating at 400 V provides substantial switching capacity for three-phase power distribution applications.

Reliable Motorised Power Changeover
Motorised changeover switches allow electrical loads to be transferred between alternative power sources using electrical control rather than requiring routine manual switching at the switchboard. The ABB OTM315E3CM24D combines a motorised mechanism with I-0-II open-transition switching for controlled source selection in three-phase low-voltage distribution systems.
The 24 V DC motor operating supply makes this model particularly suitable for installations using low-voltage DC control circuits. Its 315 A three-pole switching arrangement provides a practical solution for integrating remote source changeover into industrial switchboards, generator systems and commercial power distribution equipment.
Typical Applications
- Main and standby power supply changeover systems.
- Generator and mains supply switching installations.
- Industrial low-voltage distribution switchboards.
- Commercial building electrical distribution systems.
- Manufacturing and process plant power systems.
- Remote source-selection and transfer systems.
- Three-phase installations using 24 V DC control circuits.
