1. Best conductivity 12v fuse block has positive and negative electrodes. The maximum operating voltage of the terminal is 32V DC, the rated input current is 100A, and the maximum operating voltage of this fuse box is 30A per circuit and per panel. 2. Safety materialThe product uses PBT flame retardant and high and low temperature resistance material to meet the conditions (fuse holder has good mechanical strength, insulation, heat resistance and flame retardant, should not produce fracture, deformation, combustion and short circuit and other phenomena in use). 3. LED Safety indicator When a blown fuse is detected, the red LED warning light immediately lights up. It is r and easier for you to check and replace fuses. 4. 1 in 8 outProduct 1 in 8 out design, you can directly connect a line to the positive electrode of the battery, a line to the fuse box, and then separated by the fuse box 8bit terminals are connected to the positive electrode of different electrical appliances.
