3.8 Fusing
The APD8F contains eight replacable fuses - one for each output zone. When replacing these fuses,
only the equivalent type and rating are to be used. The APD8F utilizes commonly available
automotive blade-type fuses (Type ATC). All fuses are rated at 3A (ATC-3).
Only the APD8F contains fuses. The APD8 uses output PTCs.
