Other Range of Transfer Switches ZTS ZTSD ZTG ZTGD

 

The GE Zenith Controls ZTX Series of transfer switches is built for residential and light commercial 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. GE Zenith ZTX switches are equipped with the R-M3 control panel (Module 3) as standard. This microprocessor control 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) All time delays are fixed. The unit is available in open type, NEMA 1 or NEMA 3R enclosures. The R-M4 control option (Module 4) adds a user interface and functionality, including: Indicating LEDs for power availability, switch position and load energized Pushbuttons for test, engine start (manual), generator exerciser and diagnostic reset Selectable 7, 14, 21 or 28 day (factory set 28 days) generator exerciser timer Diagnostic LED indications Additional options include: A3/A4 Auxiliary contacts (1 each) closed in utility and generator positions Special timer settings Electrical Ratings Ratings 40 to 400 amps (2, 3 or 4 pole) UL 1008, CSA and IEC listed to 240 VAC 50/60 Hz Double-throw, mechanically interlocked contactor mechanism Electrically operated, mechanically held Designed for standby applications
