Transfer switch
40 - 400 A, 120 - 480 V | ZTX series
GE Digital Energy
The Zenith 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.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 (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.
# A3/A4 Auxiliary contacts (1 each) closed in utility and generator positions
# Integrated battery charger 1.5A/12V
# Special timer settings
