(1) The voltage and current ratings listed are valid up to 1,000 m (3,300 ft). Please refer to Tabl e 3 for ratings above this altitude.
(2) The IEC rating at 7200V (RMS Sym.) is 5300 A / 66 MVA.
(3) Control voltage, as measured at the input of the IntelliVAC or IntelliVAC Plus control module.
(4) Provided that regular maintenance is performed, as detailed in this manual.
(5) A contactor drop-out delay may be configured with the IntelliVAC or IntelliVAC Plus control module (refer to publications 1503-UM053_-EN-P
and 1503-UM054_-
EN-P).
(6) The full Altitude range is available with the IntelliVAC or IntelliVAC Plus control module only, and the IntelliVAC or IntelliVAC Plus is to be configured accordingly (refer
to publications 1503-UM053_-EN-P
and 1503-UM054_-EN-P). The standard mechanical latch contactors, if used with electro-mechanical control, are designed
for -1000...1000 m (-3300...3300 ft). Higher altitudes are possible by changing the contactor return springs (refer to Figure 5
for suitable catalog numbers).
(7) The number of contactor auxiliary contacts depends on the contactor type. Some of the contacts are used in the typical control schemes used.
