TDL 4FB – 4 Way Fuse Board

4 Way 3 Amp Fuse Board The 4 Way Fuse Board has 4 individual fused outputs. Each fuse has an associated LED to indicate that the fuse is operative. The LED illuminates green for normal positive 12Vdc operation, red for negative polarity and amber for AC voltages up to 24Vac supply. The board can be used for the protection of 24Vac cameras too but the fuses need to be changed to 1amp ( and as noted earlier ) the LED's will illuminate amber. This unit also fits on the TDL Mounting Base system to ensure a neat and tidy installation. Features
