A dependable fuse can mean all the differences in the world. In a vehicle, it can mean the difference between on my way there and I'm going to need a ride cause my car is in the shop. Littelfuse’s 30EV1K fuse series offers reliable protection for high voltage circuits up to 1,000 volts in electric and hybrid vehicles. Current rating options from 150 to 225 amps are available with respective melting points from 60,000 to 164,000 I2t.
The 30EV1K series provides protection when it’s needed with opening times from 5 hundredths of a second at 500 percent of rating to 300 seconds at 200 percent of rating. Zinc alloy end caps exhibit durability and M8 bolt-down copper alloy terminals aid in corrosion resistance while the melamine housing meets UL 94 flammability ratings suitable for installation in engine and motor compartments.
