Automatic Transfer Switches
ZTG Series - Standard (Open) or Delayed Transition

ZTG Series - Standard (Open) or Delayed Transition

The Zenith ZTG Series of transfer switches are built for general purpose commercial and industrial applications requiring the dependability and ease of operation found in a power contactor switch. The ZTG series uses the MX150 microprocessor control system, which includes features specified on a general purpose commercial and industrial applications. It also provides an intuitive user interface, communications capability and self diagnostics. The ZTG Series is available in a full range of ampere, voltage and pole configurations, along with many commonly requested options and features.

 

 

Configurations

 

  • ZTG - Standard (Open) Transition
    The Zenith ZTG transfer switch is used in general and mixed load applications.

 

  • ZTGD - Delayed Transition
    The Zenith ZTGD transfer switch is used for the transfer of large motor or inductive loads.

Features and Benefits

  • Close differential under-voltage sensing of the normal source
  • Voltage and frequency sensing of the emergency source
  • Test switch (fast test/load/no load) to simulate normal source failure - automatically bypassed should the emergency source fail
  • Double throw, interlocked operation
  • Electrically operated, mechanically held by a simple, over-center mechanism
  • Segmented silver tungsten alloy contacts with separate arcing contacts on 600 amps and above
  • Arc quenching grids, enclosed arc chambers and wide contact air gap for superior source-to-source isolation on all units
  • Control circuit disconnect plug and drive inhibit switch for safe maintenance
  • Components accessible for inspection and maintenance without removal of the switch or the power conductors
  • Mechanical indicator and contact chamber cover designed for inspection, safety and position designation
  • Offering a Warranty Period of twenty-four (24) months or two years from the date of shipment
