Drive Short-Circuit Rating
This drive has undergone the UL short-circuit test, which certifies that during a
short circuit in the power supply the current flow will not rise above 30,000 amps
maximum at 240 V for 200 V class drives and 480 V for 400 V class drives.
• The MCCB and breaker protection and fuse ratings (refer to Table D.1 ) shall be
equal to or greater than the short-circuit tolerance of the power supply being
used.
• Suitable for use on a circuit capable of delivering not more than 30,000 RMS
symmetrical amperes for 240 V in 200 V class drives (up to 480 V for 400 V
class drives) motor overload protection.
