Fuses (UL Recognized)
UL Recognized 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 on page 69.
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 must not be used.
