0v-250v universal fuse tube is used as long as the voltage does not exceed 250V, including 12V and 24V, 36V, 48V, etc., which is applicable to household appliances, electronic appliances, automobiles, instruments, electronic toys, etcFuse common sense:2 fuse copper cap above his head there is a lettering, such F1A250V says is 1A fuse, A is a current unit, 1A fuse is to withstand the maximum value! Length is 20 mm, 5 mm in diameter is 5 × 20 fuses. Length of 30 mm and a diameter of 6 mm is 6 × 30 fuse. If you do not know a few A fuse, can be calculated using the electrical power of the own current fuse out size is calculated by dividing the number of watts of electrical voltage = current; can be appropriate to increase the current; for example, 500W electrical voltage 220V, select the fuse 500 in addition to 220 = 2.27A current,
