Why Choose the ABB OTM1600E4CM24D Motorised Changeover Switch?
The ABB OTM1600E4CM24D is a heavy-duty motorised changeover switch designed for reliable transfer between two electrical power sources in demanding industrial and commercial power distribution systems. As part of the ABB OT motorised changeover switch range, it combines a high 1600 A current rating with electrically operated source changeover for substantial low-voltage installations.
This four-pole switch uses an open-transition I-0-II changeover arrangement, disconnecting one supply before connecting the alternative source. Its integrated motor drive enables remote operation from an external control system, while the supplied handle provides manual operating capability when local or emergency switching is required.
With a rated operational current of 1600 A, a 4-pole configuration and a 24 V DC motor operating voltage, the OTM1600E4CM24D is suitable for high-current mains, generator and alternative supply changeover systems. The fourth pole is switched simultaneously, making the unit suitable for installations where the neutral conductor must be transferred together with the three phases.

Reliable Motorised Power Changeover
Motorised changeover switches allow electrical loads to be transferred between alternative power sources using remote control signals rather than requiring routine manual switching at the switchboard. The ABB OTM1600E4CM24D uses an open-transition arrangement in which the connected source is disconnected before the alternative source is engaged.
The four-pole configuration switches all three phases together with the fourth pole, supporting systems requiring simultaneous neutral changeover. A handle for manual operation, terminal bolt hardware and control-circuit connectors are supplied with the switch, supporting installation and local operation 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 power distribution systems.
- Manufacturing and process plant electrical systems.
- Infrastructure and critical power distribution installations.
- Four-pole systems requiring switched-neutral changeover.
