Quick Guide For Selecting Between Gg And Ar Fuses - ABB ACS800 Hardware Manual

Quick guide for selecting between gG and aR fuses

The table below is a short cut in selecting between gG and aR fuses. The
combinations (cable size, cable length, transformer size and fuse type) in the table
fulfil the minimum requirements for the proper operation of the fuse.

Note 1: The supply transformer minimum power in kVA is calculated with a z
frequency 50 Hz.
Note 2: The table is not intended for transformer selection - that must be done separately.
