Why Choose the ABB OTM1000E3CM230C 1000 A 3-Pole Motorised Changeover Switch?
The ABB OTM1000E3CM230C is a heavy-duty 1000 A 3-pole motorised changeover switch designed for controlled transfer between two electrical supplies in high-current low-voltage distribution systems. Part of the ABB OT Changeover Switches range, it combines electrically operated source transfer with provision for manual operation.
The OTM1000E3CM230C provides I-O-II open-transition switching, ensuring electrical separation between the two sources during transfer. Its integrated motor operator uses a 220–240 V AC control supply, making the switch suitable for remotely controlled and automated source-changeover systems.
With a 1000 A AC-21A/AC-22A rating at up to 415 V, a 680 kVA rated power at 400 V and a 3-pole configuration, the OTM1000E3CM230C is designed for substantial three-phase installations. It is supplied with a handle for manual operation, terminal bolt hardware, control-circuit connectors, a handle storage clip and spare fuses.

Motorised Open-Transition Power Source Changeover
Motorised changeover switches allow source-transfer operations to be performed electrically rather than relying solely on local manual switching. The ABB OTM1000E3CM230C combines a motor-driven mechanism with I-O-II open-transition switching, making it suitable for control systems that initiate changeover remotely or automatically.
The switch also includes a manual operating handle, allowing local operation when required. Its 1000 A three-pole switching capacity, 220–240 V AC motor supply and 50 kA short-time withstand capability make it suitable for substantial industrial and commercial power-distribution assemblies.
Typical Applications
- Motorised mains and generator changeover systems.
- Automatic transfer and source-selection assemblies.
- High-current industrial distribution switchboards.
- Three-phase low-voltage power distribution systems.
- Industrial plant and infrastructure power systems.
- Remote-controlled alternative supply switching.
