ABB TruONE Automatic Transfer Switches

ABB’s TruONE automatic transfer switch incorporates both switch and controller in one seamless unit, a self-contained design that minimizes wires and connections.

The streamlined design results in a substantial reduction in installation time — up to 80%. In addition, TruONE™ ATS units’ predictive maintenance and modular components can help reduce downtime and service costs.

Easy to install — TruONE™ is the first automatic transfer switch to put it all together, including the controller with detachable HMI. It can be installed with a single wire using standard enclosures.
Safety and protection — TruONE™ enables emergency manual operation — even under load — without opening the panel door when the HMI is mounted to the ATS frame. The HMI can detach from the frame for door mounting, offering more flexibility for the panel designer. Best of all, there’s no need for connecting dangerous line voltages to the door.
Optimum interface — TruONE™ features cloud-based connectivity through the ABB Ability™ Electrical Distribution Control System. ABB Ability simplifies implementation with other ABB devices, ensuring one common user interface.
Features a wide voltage range from 200 to 480 VAC (with +/-20% tolerance)
Safe and reliable operation during dramatic variations in temperature (-25 to +70°C)
Tolerant of vibrations (acc. IEC 60068-2-6) and shocks (acc. IEC 60068-2-27)
Automatic commissioning capabilities, with premade configuration files that can be uploaded from a PC

TruONE™ features plug-in factory and field-mount accessorizing, so you don’t need extra space inside the panel. Even in the case of specialized customer needs, you can use standard cabinets.
