Automatic transfer switch GE Automatic Transfer Switches 120 - 600 V; 40 - 400 A
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.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.
The unit is available in open type, NEMA 1 or NEMA 3R enclosures. Additional options include:
