ZTS Series

Withstand Ratings

GE Zenith ZTS Series Automatic Transfer Switches have been subjected to an extensive test program to show that they comply with and exceed UL 1008 standards, as well as the various performance specifications used by most government agencies and major electrical engineering firms throughout the world. The primary test to ensure the quality and dependability of an automatic transfer switch is its ability to close into and withstand high fault currents. The table shows the Underwriters Laboratories and Canadian Standards certified withstand and closing current ratings in symmetrical RMS amperes at 480 and 600 volts AC.

1.For each rating attained in above table, the heat run was performed after the overload and endurance tests.

2.These models also listed for 100% tungsten lamp loads.

3.Consult factory for coordinated breaker types and ratings.

4.All transfer switches are rated in coordination with the protective device installed. Lower rated devices than those shown may be utilized and the system rated accordingly.

5.Consult the factory for IEC ratings.
