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 31,000 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 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 31,000 RMS symmetrical
amperes for 240 V in 200 V class drives (up to 480 V for 400 V class drives) motor overload
protection.
