OTM80F4CMA230V ABB 80A 4-Pole Motorised Changeover Switch 230V

Why Choose the ABB OTM80F4CMA230V Motorised Changeover Switch?

The ABB OTM80F4CMA230V is an 80 A four-pole motorised changeover switch designed for controlled transfer between two electrical power sources. Part of the ABB OT motorised changeover switch range, it combines compact switching construction with an integrated motor operator for remote source selection in industrial and commercial low-voltage distribution systems.

The OTM80F4CMA230V provides open-transition changeover operation, disconnecting the active source before the alternative source is connected. Its integrated motor operator supports a broad 110–240 V AC/DC operating range, while ABB supplies a handle for manual operation, terminal hardware and male connectors for the control circuits.

With an 80 A rated current, four-pole configuration and 55 kVA rated power at 400 V, the OTM80F4CMA230V provides a compact solution for mains/generator, standby and alternative source selection. Its four-pole construction simultaneously switches the fourth pole with the other poles, supporting installations requiring four switched conductors.

Reliable Motorised Power Source Changeover

The ABB OTM80F4CMA230V provides a controlled method of transferring electrical loads between two independent power sources. Its open-transition switching arrangement disconnects the active source before connecting the alternative supply, maintaining separation between the two sources during the transfer process.

The integrated 110–240 V AC/DC motor operator enables remote source selection from a suitable transfer-control or power-management system, while the supplied direct-mounted handle provides local manual operation. Combined with its 80 A rating and four-pole simultaneous switching arrangement, the OTM80F4CMA230V provides a compact solution for motorised source-transfer installations.

Typical Applications

• Mains and generator power source changeover systems.
• Standby and emergency power distribution.
• Industrial electrical switchboards.
• Commercial building electrical distribution.
• Alternative electrical supply selection.
• Four-pole installations requiring remote motorised source transfer.
