Semiconductor Fuses

Semiconductor fuses may be used with the MCD
200 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 200 soft starters have been
tested to achieve Type 2 coordination with
