H. V HRC current-limiting fuses type W motor protection is mainly used in AC 50Hz, rated voltage 3.6-10KV, rated current up to 400A(3.6KV), 224A(7.2KV) circuit for protecting motor and power equipment from overload and short-circuit. It can also be used with load switch, vacuum contact.
It conforms to IEC282-1, IEC644, BS and GB15166.2.
When fault circuit happens, The fuse links melts, the high resistant metal wire paralleling to fuse link melts immediately at the appearance of the arc, and the sreiker jumps out to push the chained equipment contact, signaling the melting or automatically cutting the circuit. W type H. V HRC current-limiting fuse has many merits as high current limiting ablity, high breaking capacity, quick and punctual in action, reliable in performance.

Game Camera is a remotely activated camera that is equipped with a motion sensor or an infrared sensor, or uses a light beam as a trigger. Camera trapping is a method for capturing wild animals on film when researchers are not present, and has been used in ecological research for decades. In addition to applications in hunting and wildlife viewing, research applications include studies of nest ecology, detection of rare species, estimation of population size and species richness, as well as research on habitat use and occupation of human-built structures.
Game Camera, also Motion Video Camera are used to capture images of wildlife with as little human interference as possible.Since the introduction of commercial Infrared-Triggered Cameras in the early 1990s their use has increased. With advancements in the quality of camera equipment this method of field observation has become more popular among researchers.Hunting has played an important role in development of camera traps, since hunters like to use them to scout for game. These hunters have opened a commercial market for the devices which have led to many improvements over time.
