5.9.3 Recommended Fuse Ratings for UL Installation

The table values are calculated using correction factors for a 40 °C (104 °F) ambient operating condition and using cables with a
minimum insulation rating of 90 °C (194 °F).
UL Approval is valid for maximum input voltage of 600 V. Per UL508A, the short-circuit current rating (SCCR) is as follows:
• Enclosed drives with a fusible disconnect or fusible disconnect and contactor option have 65 kA SCCR at the rated voltage.
• Enclosed drives with single switchgear (mains contactor only or non-fusible disconnect only option) have a 5 kA SCCR, but can
reach 65 kA if the recommended Class fuses are used upstream.
• Enclosed drives with the MCCB option have a 65 kA interrupting rating for 380–480 V, and a 50 kA interrupting rating for525–690 V.
