• Semiconductor fuses may be used with MCD soft starters. Use
of semiconductor fuses will provide Type 2 coordination and
reduce the potential of SCR damage due to transient overload
currents and short circuits. MCD soft starters have been tested
to achieve Type 2 coordination with semiconductor fuses. The
following table provides a list of suitable Bussman fuses. If
selecting alternate brands ensure the selected fuse has a lower
total clearing I2t rating than the SCR, and can carry start current
for the full start duration.
