Fusing

External power supply and 24 V fusing

Non renewable cartridge fuses must be used with finger safe fuse holders according to IEC 60529.

UL/cUL cartridge fuses: Class J, 600 VAC 200 kA, time-delay. The fuse must be UL and cUL listed. The voltage rating of the external fuse(s) shall be at least equal to the mains voltage.

CE cartridge fuses: types gS(gRL) or gG, 400 V/500 V, time-delay

Cartridge Fuses	Ampere rating	UL Region	CE Region
MKD-C003007-NAEC: External AC power supply fusing (FN1/2/3)	60 A (Time-Delay)	example Mersen: AJT 60, 60A	example Siba: type gS/gG, D02, 63A
MKD-C001007-CAEC: External AC power supply fusing (FN1/2/3)	20 A (Time-Delay)	example Mersen: AJT 20, 20A	example Siba: type gS/gG, D02, 20A
External 24 VDC supply fusing (FA1)	40 A (Time-Delay)	example Mersen: TR40R, 40A	example Mersen: D02GG40V40/10, 40A

Ampere rating for operation with full application power. Low coincidence factor may allow reduction of fuse ampere rating.
