Why Choose the ABB OTM200E4CM24D Motorised Changeover Switch?
The ABB OTM200E4CM24D is a robust motorised changeover switch designed for reliable transfer between two electrical power sources in industrial and commercial low-voltage distribution systems. As part of the ABB OT motorised changeover switch range, it combines a 200 A current rating with electrically operated changeover functionality for dependable power-source switching.
This four-pole switch provides I-0-II changeover operation, allowing a load to be switched between two alternative supplies with a defined OFF position between them. Its integrated motor operator enables remote electrical switching, while the supplied handle provides manual operating capability when local control is required.
With a rated current of 200 A, a 4-pole configuration and a 24 V DC motor operating voltage, the OTM200E4CM24D is suitable for mains and standby power systems, generator changeover installations and industrial distribution boards. The four-pole configuration enables simultaneous switching of three phases and neutral where required.

Reliable Motorised Power Changeover
Motorised changeover switches allow electrical loads to be transferred between alternative power sources using remote electrical control rather than requiring routine manual switching at the switchboard. The ABB OTM200E4CM24D combines a motorised mechanism with I-0-II switching to provide controlled source selection for low-voltage distribution systems.
The switch includes a handle for manual operation, a bolt kit with nuts and washers for the terminals, male connectors for the control circuits, a storage clip for the handle and spare fuses. These features support straightforward integration into electrical switchboards while retaining convenient local operating capability.
Typical Applications
- Main and standby power supply changeover systems.
- Generator and mains supply switching installations.
- Industrial low-voltage distribution boards.
- Commercial building electrical distribution systems.
- Manufacturing and process plant power systems.
- Remote source-selection and transfer systems.
- Four-pole applications requiring switched-neutral changeover.
