Littelfuse claims first automotive-grade fuse rated to 1,000V DC
Intended for electric vehicle (EV) power system applications which require robust over-current protection in harsh environments, Littelfuse introduced the EV1K series fuse, claiming it is the first 1,000V DC automotive-grade protection device for passenger cars and commercial EVs.
Fuses in the series are designed and tested to meet the over-current circuit protection needs of the EVs’ high voltage power supplies. They are suitable for use in on-board chargers (OBCs), battery distribution units (BDUs), battery packs, DC/DC converters, traction motor inverters and auxiliary loads.
“There is a clear need for more robust safety solutions as the e-Mobility market transitions from 500 to 800V DC pack voltages,” said Juergen Scheele, vice president, Business Development xEV/AEB at Littelfuse. The EV1K series fuses are designed to withstand severe automotive environments, providing 1,000 V DC rated automotive-grade solutions ranging from 60 to 125A. Fuses up to 600A are also under development, added Scheele.
Key benefits offered by the EV1K series fuse include a compact body size of 25 x 73mm with end caps incorporating integrated bolt-down terminals for a housing which is durable against mechanical vibration and shock. It also increases product life and longevity, claimed Littelfuse.
Operating temperature ranges from -55 C to +125 degrees C and the design also provides humidity resistance.
The series of environmentally-friendly fuses are RoHS-compliant, halogen-free, and 100% Pb (lead) -free.
The EV1K series fuse is available now. Sample requests can be placed through authorised Littelfuse distributors worldwide.
Littelfuse is an industrial technology manufacturing company operating across more than 15 countries, serving over 100,000 end customers. The company’s products are found in a variety of products in the industrial, transportation and electronics markets.
