How many fuse sizes in Bussmann?

You may see vary fuse in many different situations: In Battery protection, In DC inverters, in Electric Vehicle(EV), In IGBT’s, In UPS，at home….

You are maybe confused there are many fuse sizes in same voltage, same current. How to select?

170M1367,Bussmann fuse 100A 690V	170M2714,Bussmann fuse 100A 690V	170M3662,Bussmann fuse 100A 690V	100FE,100A 690V AC TYPE T Bussmann fuse

So, how many fuse sizes does fuse with?

1：Divide according to shape: in simple, there are 2 sizes:

1), Square Body

2-1), Round body(US style)

2-2), Round body(British Style)

2, If base on fuse standards, Bussmann fast acting fuses are grouped with 4 standards:

•      US Style — North American blade and flush-end style

    For example:FWP-100A

•      European standard — square body

    For example:170M6466

•      British Standard — round body BS88

    For example: 180FM

•      Ferrule fuses —

        For example:FWA-2000AH
