Feature:

The LRD product series are designed to reduce the device's resistance at the same hold current rating. The smaller thermal mass of these devices also provide benefit 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
