Zenith ZTG series Automatic Transfer Switches
Commercial and Industrial applications
Powered by TruONE™ technology, Zenith ZTG 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, and an optimum interface for advanced control, connectivity, and energy efficiency.
Easy to Install and Commission
Start up in minutes, not hours.
The new Zenith ZTG 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 TruONE™ technology, no additional control wiring or troubleshooting is required onsite. 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 3 Software, even without any external power supply.
Continuous Operation
Minimize unplanned outages.
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. Say goodbye to blinking lights and stopping motors.
Advanced Data and Connectivity
Make data-driven decisions.
The Zenith ZTG 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.
Optimum Interface
Frustration-free programming.
The LCD HMI on Zenith is easily navigated, password protected, and allows access to features ranging from programmable set-points, time delays, digital I/O and exercisers to switch status, events, and diagnostics. In addition, Ekip Connect computer software is an alternative to the HMI that makes programming a cinch whether you’re in the office, or on-site. With this tool, you can import, export, or modify ATS settings via the USB port located on the HMI with no need to apply power to the unit.Specs

NOTES:
1) The Override momentary Source 1 Outage time delay prevents nuisance generator starts during momentary utility power variations; transfer time delay allows generator set to stabilize before load is applied; Transfer from Source 2 to Source 1 delay prevents needless power interruption if return of utility power is momentary; Generator stop delay allows gradual generator set cool down; Drop out Voltage sensing of utility supply provides reliable starting of generator set during brownout conditions.
2) This switch is not service entrance rated. This generally means that you need a service entrance rated device between this switch and your power company meter.
3) The standard ZTG contactor comes with 2 power poles to switch the two hot leads of a 120/240V system. It does NOT switch the neutral, which is acceptable in most areas of the USA. If there are special requirements in your area that require switching the neutral (as dictated by local codes or electrical inspectors) contact us for a quote.
4) Two normally open auxiliary contacts (1 on the utility and 1 on the emergency contactor) are available as an option. These can be used for remote indication of the switch position or to turn off loads that should not run when on generator power (such as large heat pumps or central air conditioners). To order use the drop-down menu.
5) WIRING - This switch provides a single isolated contact for controlling the genset. The contact closes when the genset is to start and run.
