For the DC-300 and DC-750 models there are 2 separated fuses, one fuse (13 amp) in the moulded plug and an internal fuse for the chiller circuit.

The DC-300 model the correct internal fuse is the "T3.15A/250V if you cannot get the T starting type, then you need to use a glass fuse of 5~6A/250V 20mm x 5mm slow blow.

The DC-750 model the correct internal fuse is the “T6.3A/250V if you cannot get the T starting type, then you need to use a glass fuse of 10A/250V 20mm x 5mm slow blow.

For the DC-2200 and DC-4000 models there is only a fuse in the plug. There is no internal fuse as the power/current is too high.
