650v dc motor drive fuse solution
Recently we help some customers designing the 650VDC power supply system in DC motor drive circuit.
Here is the high speed fuse and fuse holdersolution.
1, Mersen
A70QS500-4, A70QS125-4, A70QS175-4 series fuse with 650VDC, 700VAC voltage.
They are easily be assemblied in circuit with screws.
Also you can use A70QS80-22F which is the ferrule fuse. They are mating US222 or US222I fuse holder.
