Fuses (Iec) - ABB ACS580-01 Hardware Manual

Fuses (IEC)

gG as well as uR or aR fuses for protection against short-circuit in the input power
cable or drive are listed below. Either fuse type can be used for frames R0...R9 if it
operates rapidly enough. The operating time depends on the supply network
impedance and the cross-sectional area and length of the supply cable. For frames
R7...R9 ultrarapid (aR) fuses must be used.
Note 1: See also Implementing thermal overload and short-circuit protection on page
66.
Note 2: Fuses with higher current rating than the recommended ones must not be
used.
Note 3: Fuses from other manufacturers can be used if they meet the ratings and the
melting curve of the fuse does not exceed the melting curve of the fuse mentioned in
the table.
