Then is needs to be replaced to keep operating appliance. 2. Functions of fuse: When the circuit is out of order or abnormal, with the continuous increasing of current which probably will damage some vital or valuable components in circuit or burn circuit causing a fire, fuse will not only protect electronic devices from over current, but also prevent electronic components from being damaged caused by internal faults. Thus, each fuse has rating for it to fuse when current beyond rated specification. If fuse is placed correctly in circuit, the fuse will fuse automatically to cut off current when it gets over current or too high temperature for ensuring the safe operation of circuit. 3. This product adopts flame-retardant and environment friendly PBT material with high and low temperature resistance which completely meets the requests that fuse should have great mechanical strength, insulation property, heat resistance and flame retardancy to prevent it from breakup, deformation, burning, short circuit and other phenomena in operation. 4. The design of 12 ways allows this product to be connected with battery positive directly with a cable. Then fuse will separate 12 ports to connect different electric appliances easily and conveniently. 5. This product has design of red LED indicator light which is corresponding to each electrical appliance connecting with each fuse piece. When fuse is broken, red lights will light, which will be recognized very soon for convenient timely . 6. Enclosed stickers are gifts for you to paste on the corresponding electrical appliance according to the names on stickers. Then when fuse is broken and res LED lights, the troubled appliance will be recognized very soon for saving time and labor. 7.
