Automatic Transfer Switches
GTX Series - Standard (Open transition) IEC certified

GTX Series - Standard (Open transition) IEC certified

 

The Zenith GTX Series of automatic transfer switches (ATS) are built for light industrial and commercial critical applications requiring the dependability and ease of operation found in a power contactor switch. The GTX transfer switches are designed for standby applications, and incorporate a double-throw, mechanically interlocked contactor mechanism.
 
 
The GTX transfer switches are equipped with an optional MX70 Microprocessor Control Panel.

 

 

 

 

This microprocessor includes:

  • Undervoltage sensing (90% pickup/80% dropout) of the utility source
  • Voltage and frequency sensing of the generator source (90% voltage/95% frequency pickup)
  • Time Delay Engine Start - 3 seconds (P)
  • Time Delay Engine Warmup - Transfer to Generator - 3 seconds (W)
  • Time Delay Utility Stabilization/Retransfer to Utility - 10 minutes (T)
  • Time Delay Engine Cool Down - 5 minutes (U)
  • Indicating LEDs for power availability, switch position and load energized
  • Pushbuttons for test, engine start (manual), generator exerciser, timer bypass and program cancel
  • Wiring interconnection plug designed to prevent mis-operation errors
  • Special status annunciation of in-phase transfer and timer operation
  • Smart diagnosis program and in phase monitor
  • Selectable 7, 14, 21 or 28 day (factory set 28 days) generator exerciser timer
  • Diagnostic LED indications in logical one-line configuration. All time delays can be adjusted using MX70 software.

 

The GTX Power Panel includes:

  • Double throw and mechanically held
  • Arc quenching grids, enclosed arc chamber and wide contact air gap
  • Fast contact transfer speed less than 100ms


The unit is available in open type (non-enclosure), NEMA 1 (IP20) or NEMA 3R (IP24) enclosures.

Additional options include:

  • A3/A4 Auxiliary contacts (1 each) closed in Source 1 and Source 2 positions
