(1) The voltage and current ratings listed are valid up to 1,000 m (3,300 ft). Please refer to
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 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
he 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
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.
