GTX Series - Standard (Open transition) CCC certified

The Zenith GTX Series of automatic transfer switches (ATS) are designed for light commercial safety applications where reliability and ease of use are ideal. These automatic transfer switches are engineered for standby applications, and incorporate a double-throw, mechanically interlocked contactor mechanism.

The GTX transfer switches are equipped with theĀ MX90 Microprocessor Control Panel.

GTX Series 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 - 5 seconds (P)
  • Time Delay Engine Warmup - Transfer to Generator - 20 seconds (W)
  • Time Delay Utility Stabilization/Retransfer to Utility - 5 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
  • Special status annunciation of in-phase transfer and timer operation
  • 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 are fixed.

The unit is available in open type, NEMA 1 or NEMA 3R enclosures. Additional options include:

  • A3/A4 Auxiliary contacts (1 each) closed in utility and generator positions
  • Integrated battery charger 1.5A/12V

GTX Series MicroProcessor Scope:

  • Ratings 40 to 400 amps
  • 120/380V, 208/416V, 50/60Hz
  • CCC Certified
  • Compiles to GB/T 14048.11-2008
  • Double throw, mechanical interlocked contractor mechanism
  • Electrically operated, mechanically held
  • Designed for standby applications
