OTM1600E4CM230C ABB 1600 A 4-Pole Motorised Changeover Switch 230 V AC

Why Choose the ABB OTM1600E4CM230C Motorised Changeover Switch?

The ABB OTM1600E4CM230C 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 high-current switching capability with electrically operated changeover functionality for critical power distribution applications.

This switch provides open-transition changeover operation with a four-pole configuration, making it suitable for systems where three phases and neutral need to be switched between alternative supplies. Its integrated motorised mechanism enables remote electrical operation, while ABB also provides a handle for manual operation when local switching is required.

With a rated current of 1600 A, a 4-pole configuration and a 220–240 V AC motor supply centred on 230 V AC, the OTM1600E4CM230C is engineered for substantial low-voltage distribution installations. Its robust construction makes it suitable for switchboards, generator changeover systems and other high-current power transfer applications.

Reliable Motorised Power Changeover

Motorised changeover switches provide a practical means of transferring electrical loads between alternative power sources while allowing the switching process to be controlled remotely. The ABB OTM1600E4CM230C uses an open-transition arrangement, disconnecting one source before connecting the alternative source during changeover.

The four-pole construction allows all three phase conductors and the neutral conductor to be switched, supporting installations where complete source separation is required. Its motorised mechanism can be incorporated into power transfer control systems, while the supplied manual handle provides an alternative method of local operation.

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.
