Solar Fuse 14*85mm 1500VDC Fuse

The CFPV-63L 14×85mm 1500VDC solar fuse link is designed for overcurrent protection in photovoltaic DC circuits where high voltage and variable current conditions are present. 

High DC breaking capacity for photovoltaic short-circuit fault conditions

Stable time-current characteristics under continuous solar load cycles

Controlled I²t energy let-through to protect inverters and downstream components

Thermal stability across wide environmental operating conditions (-40°C to +85°C typical PV environments)

Fuse element: Silver / copper alloy for controlled melting behavior
Tube body: High-strength ceramic for arc containment
Filling medium: Quartz sand for DC arc extinction
End caps: Conductive metal terminals with low resistance connection 

PV String Protection
Protects individual photovoltaic strings from reverse current and short-circuit faults in 1500VDC systems.
Combiner Box Protection
Provides circuit isolation in DC combiner boxes, preventing fault propagation across PV arrays.
Solar Inverter DC Protection
