Contact us with your specs and configuration needs. • Standard Transition • 40-400 Amp, 120-480 Volt Ratings (2, 3 or 4 Pole) • 50 or 60 Hz • UL 1008, CSA and IEC listed to 480 VAC • Seismic Compliance to IEEE-693-2005 and IBC-2006 • Double throw, mechanically interlocked contactor mechanism • Electrically operated, mechanically held • Designed for standby applications GE’s Zenith ZTX switches are equipped with the MX60 control panel. This microprocessor control includes: • Undervoltage sensing (90% pickup/80% dropout) of Source 1 (normal) • Voltage and frequency sensing of Source 2 (emergency) (90% voltage/95% frequency pickup) • Time Delay Engine Start (P) - 5 seconds • Time Delay Engine Warmup (W) - Transfer to Emergency (Source 2) - 20 seconds • Time Delay Utility Stabilization/Retransfer to Utility (Source 1) (T) - 5 minutes • Time Delay Engine Cool Down (U) - 5 minutes All time delays are fixed (non-adjustable). The unit is available in open type, NEMA 1 or NEMA 3R enclosures. The MX60 control adds a user interface and functionality, including: • Indicating LEDs for source availability and switch position • Pushbuttons for test, exerciser set, 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 (Source 2) with or without load exerciser timer • Diagnostic LED indications in logical one-line configuration GE’s Zenith ZTX Series Automatic Transfer Switches are designed for residential and light commercial critical/non-life safety applications requiring the dependability and ease of operation found in a power contactor switch.
