GTX Series Automatic Transfer Switch Overview GE’s GTX Series Automatic Transfer Switches are designed for critical industrial, residential, and commercial applications requiring the dependability and ease of operation found in a power contactor switch. • Programmable time delay engine cool down (U) - 3 seconds factory default setting • All time delays can be adjusted using MX70 software • Indicating LEDs for power availability, switch position, and load energized in a logical one line configuration • Pushbuttons for test, engine start (manual), generator exerciser, timer bypass and program cancel MX70 Microprocessor Control Panel • Special status annunciation of in-phase transfer and timer operation • Smart diagnosis program and in phase monitor GTX Transfer Switches are Equipped with an Optional MX70 Microprocessor Control Panel This microprocessor control includes: • Undervoltage sensing (90% pickup/80% dropout) of Utility source • Voltage and frequency sensing of generator source (90% voltage/95% frequency pickup) • Selectable 7, 14, 21 or 28 day (factory set 28 days) generator exerciser timer Enclosure Type The unit is available in: • Power Panel Only • Open Type (non-enclosed, but with a controller) • NEMA 1 (IP20) • NEMA 3R (IP24) • Time Delay Engine Start (P) - 3 seconds • Time Delay Engine Warmup (W) - Transfer to Generator - 3 seconds • Time Delay Utility Stabilization/ Retransfer to Utility (T) - 10 minutes Additional Options Include: A3/A4 Auxiliary contacts (1 each) closed in Source1 and Source 2 positions Advantages • True double throw operation where the single Solenoid Design is inherently inter-locked and prevents contacts from inadvertently stopping between sources or from being in contact with both sources at the same time. • Highly reliable, Low MTBF (mean time between failure) • Special wiring plug design prevents misoperation • Smart diagnostic program and inphase monitor (MX70 option) • Arc quenching grids, enclosed arc chamber and wide contact air gap • Neutral pole break-lastclose-first design,neutral contact is on the same shaft as other poles • Ease of op
