Fuse
HFS Harmonic filters need external over-current protection for compliance with UL/cUL standard.
Fuses and associated fuse holders must be UL listed and rated for 100kA SCCR supplies.
Please refer to requested fuse current ratings for UL class J and in full version user manual, where UL
compliance is not mandatory, for IEC class gG. The fuse rating is independent of the supply voltage.
