Zenith T-series - Automatic Transfer Switches


Zenith and ABB have over 150 years of combined experience in power switching technologies. Now under ABB, Zenith is bringing you the next generation of automatic transfer switch technology designed to increase system reliability and provide the easiest possible user experience.

Powered by TruONE™ technology, Zenith T-series automatic transfer switches incorporate switch and controller in one seamless, self-contained unit, reducing the number of wires and connections. This design saves room in the enclosure and minimizes the potential for connection failures. In addition, the design incorporates modular components to reduce downtime and service costs.

Finally – what matters most – you can count on Zenith for continuous power flow and installation longevity. This new generation of ATS owes its robustness to its innovative contact design, developed from years of careful engineering and countless hours in testing.

We’re taking Zenith ATS performance to new heights.

Easy to Install and Commission

The new Zenith series weighs up to 30% less than comparable ATS models but has up to 25% more wire-bending space, making it especially easy for contractors to install.

Once sources are connected, an innovative auto-configure function via the HMI sets electrical system parameters in seconds. Because of breakthrough ABB technology, no additional control wiring or troubleshooting is required on-site. And any programming changes can be done from the HMI with a few keystrokes, making commissioning quick and painless. You can even configure Zenith ZTG on site before installation – using a laptop with Ekip Connect software, even without any external power supply.


Continuous Operation

Zenith ATS solutions are tested to last up to 6,000 cycles. Based on 10 transfers per month, that’s 50 years of reliable operation! If things ever do go wrong, all critical modules are customer-replaceable to simplify service and significantly reduce downtime and service costs

Advanced Data and Connectivity

Zenith ATS now features cloud-based connectivity through the ABB AbilityTM Energy and Asset Manager. ABB Ability simplifies implementation and use of Zenith transfer switches in coordination with other ABB devices, ensuring one common user interface and one common software environment. Market-leading modular communication with seven protocols ensures easy installation and connectivity now and far into the future.
