The GE Zenith Controls ZTX Series of transfer switches is built for residential and light commercial critical/non-life safety applications requiring the dependability and ease of operation found in a power contactor switch.  The ZTX transfer switches are designed for standby applications, and incorporate a double-throw, mechanically interlocked contactor mechanism.

The ZTX transfer switches are equipped with the MX60 Control Panel as standard.  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 - 5 seconds
  • 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
