Fuses (Ul) - ABB ACS880-04 Hardware Manual

182 Technical data

Fuses (UL)

UL fuses for branch circuit protection per NEC are listed below. Check that the operating
time of the fuse is below 0.1 seconds. The operating time depends on the fuse type,
supply network impedance and the cross-sectional area, material and length of the supply
cable. The fuses must be of the "non-time delay" type. Obey local regulations.

Note 1: See also Implementing thermal overload and short-circuit protection
Note 2: In multicable installations, install only one fuse per phase (not one fuse per conductor).
Note 3: Fuses with higher current rating than the recommended ones must not be used. Fuses with lower
current rating can be used.
Note 4: Fuses from other manufacturers can be used if they agree with the ratings and the melting curve of the
fuse does not exceed the melting curve of the fuse mentioned in the table.
