Littelfuse's Class J Fuses Provide Maximum Protection in a Small Footprint

When space is limited, but maximum protection is imperative in HVAC/R applications, Littelfuse has your back with their UL Class J fuses.

Available up to 600 A , Class J fuses provide the protection of a Class RK1 fuse in a much smaller footprint. With a reliable overcurrent interruption of up to 200 kA, Class J fuses can be used for a wider range of HVAC/R applications, reducing inventory requirements.

To learn more about Class J fuses, visit Littelfuse online at or contact your Electra Sales of North Texas or Oklahoma representative.
