The LRD product series are designed to reduce
the device’s resistance at the same hold cur-
rent rating. The smaller thermal mass of these
devices also provide benefi t of faster trip time and
increase the battery safety level. The LRD devices
are ideally suited for battery packs used for
portble computer and camcorder applications.
