Short-circuit withstand
strength (IEC 61439-1) Maximum allowable prospective short-circuit current is 65 kA when by the
fuses given in the fuse table. For the maximum allowable prospective short-
circuit current with circuit breakers, see section
Protecting the drive and input
power cable in short-circuits on page 69 .
Short-circuit current protection
(UL 61800-5-1) The drive is suitable for use on a circuit capable of delivering not more than
100,000 rms symmetrical amperes at 600 V maximum when protected by
fuses given in the fuse table.
Short-circuit current protection
(CSA C22.2 No. 14-05) The drive is suitable for use on a circuit capable of delivering not more than
100 kA rms symmetrical amperes at 600 V maximum when by the fuses
given in the fuse table.
