Short Circuit Capability: The rated short time withstand current of
ACx 600 is 50 kA 1 s.
Measured according to US standards ACS 604 / ACS 607 (100...400 kVA):
Suitable for use in a circuit capable of delivering not more than 65 kA rms
symmetrical amperes at 480 V maximum (500 V units), and at 600 V
maximum (690 V units).
Frequency: 48 to 63 Hz, maximum rate of change 17%/s

Maximum Recommended Motor Cable Length: 300 m (980 ft). This
is the cumulative length in case of parallel connected motors. For ACx
601-0005-3 to ACx 601-0016-3, ACx 601-0006-5 to ACx 601-0020-5,
ACx 601-0009-6 to ACx 601-0020-6, if the motor cable length exceeds
70 metres (230 ft), an ABB representative should be consulted.
Motors larger than 90 kW (125 HP) Motors: Insulated bearing at non-
driven end is recommended.
