Why Choose the ABB OTM630E3CM48D Motorised Changeover Switch?
The ABB OTM630E3CM48D is a heavy-duty 630 A three-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 high-current switching capability with an integrated motor operator for remote source selection in industrial and commercial electrical distribution systems.
The OTM630E3CM48D provides open-transition changeover operation, ensuring one power source is disconnected before the alternative source is connected. It is supplied with a handle for manual operation, providing local switching capability alongside its motorised operation, while terminal hardware and control-circuit connectors support installation within power distribution assemblies.
With a rated current of 630 A, a three-pole configuration and a 48 V DC motor operating voltage, the OTM630E3CM48D is suited to mains/generator transfer, standby power distribution and alternative supply selection. Its rated power at 400 V is 435 kVA, making it suitable for demanding three-phase power-transfer applications.

Reliable Motorised Power Source Changeover
Motorised changeover switches such as the ABB OTM630E3CM48D provide a controlled method of transferring electrical loads between two independent power sources. Its open-transition mechanism disconnects the active source before connecting the alternative source, maintaining electrical separation between the supplies during the transfer process.
The integrated 48 V DC motor operator enables remote switching from a suitable transfer-control or power-management system, while the supplied manual handle provides local operating capability. Combined with its 630 A rating and three-pole construction, the OTM630E3CM48D provides a practical solution for demanding three-phase source-transfer installations.
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.
- Three-phase power transfer installations requiring remote motorised operation.
