Why Choose the ABB OTM630E4CM230C Motorised Changeover Switch?
The ABB OTM630E4CM230C is a heavy-duty motorised changeover switch designed for dependable 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 630 A current rating with four-pole switching for demanding power-transfer applications.
This four-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 source selection, while the supplied handle provides manual operating capability when local control is required.
With a rated current of 630 A, a 4-pole configuration and a 220–240 V AC motor operating voltage, the OTM630E4CM230C is suitable for mains and standby systems, generator changeover installations and high-current distribution switchboards. Its 435 kVA rating at 400 V supports substantial power-transfer applications.

Reliable Motorised Power Changeover
Motorised changeover switches enable electrical loads to be transferred between alternative power sources through remote electrical control. The ABB OTM630E4CM230C uses an I-0-II open-transition arrangement, providing a defined OFF position and ensuring the active source is disconnected before the alternative source is connected.
ABB supplies the OTM630E4CM230C with an OTV800ECMK handle for manual operation, an M12 × 40 mm bolt kit with nuts and washers for the terminals and male connectors for the control circuits. A storage clip for the operating handle and spare fuses are also included, supporting practical installation and maintenance within high-current power distribution assemblies.
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.
- High-current four-pole power distribution applications.
