Semiconductor fuses
SITOR fuses can be used as an alternative to UL fuses. Here too, the relevant data has
been included in the UL reports. Protection of the semiconductors is much better when
SITOR semiconductor fuses are used (comparable with type of coordination type 2).
The following applies to UL applications:
SITOR fuses are not feeder protective devices but only "special purpose fuses".
