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

GTX Series - Standard (Open transition) IEC certified

The Zenith GTX Series of automatic transfer switches (ATS) are built for light commercial critical/non-life safety 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 the MX90 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 - 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.
• Double throw and mechanically held
• Arc quenching grids, enclosed arc chamber and wide contact air gap
• Neutral pole break-late-close-first design, neutral contact is on same shaft as other poles
• MX70 controller proven high reliability
• Smart diagnosis program and in phase monitor
• Special wiring plug design prevent misoperation
• Fast contact transfer speed less than 100ms
• IEC60947-6-1

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
