= 2.7 kA
The calculated short-circuit current 2.7 kA is higher than the minimum short-circuit
current of the drive aR fuse type 170M3817 (900 A). -> The 690 V aR fuse (Bussmann
170M3817) can be used.
Fuses (UL)
The UL Listed fuses in this manual are required for branch circuit protection and
required per NEC. The drives are suitable for use on a circuit capable of delivering
not more than 100 kA symmetrical amperes (rms) at 480 V maximum when
protected by the fuses described below.
ABB recommends Class T fuses listed below. Also allowed are UL Listed 248-8
Class J fast acting, time delay, and high speed fuses, 248-4 Class CC fast acting
fuses and 248-17 Class CF fast acting and time delay fuses of the same nominal
voltage and current rating.
Refer to notes below the tables.
