Class J Fuses

Class J Fuses

Littelfuse offers three types of current-limiting Class J fuses to meet the need for circuit protection in industrial and electrical power generation and transmission applications. Fast-acting JLS series fuses provide space-saving overload and short-circuit protection in industrial and power conversion applications. JTD time-delay fuses employ POWR-PRO® technology to ensure very high interrupting ratings and are specifically designed for use where space is limited. JTD_ID fuses share the same features and benefits of JTD series fuses but also feature blown-fuse indicators.
