Solar PV fuse: Size:10x38mm / 14x51mm /PVNH , Rated Voltage: 1000Vdc , Current:1-20A/15-32A /32-160A. Pure silver fuse element, 95% ceramic tube and quartz sand.
1000V DC loading capacity
High breaking capacity
Low overloading protection capacity and 1.35 times of rated current
The highest applicable ambient temperature reached 120° C
Compact overall dimension: 10 X 38mm
The conditions for necessity and function of fuse protection:
if the fault current caused by short circuit in PV array can not be
effectively broke, which will be harmful for PV panel and cable,
strong DC arc will formed in the circuit.
