Frequently Asked Questions
What is the primary function of a photovoltaic (PV) fuse?
A photovoltaic fuse is designed to interrupt low-level overcurrents generated by faulted PV strings (reverse current, multi-array faults) to protect the solar panels, system wiring, and prevent hazardous conditions such as fire.
Why should I use special DC PV fuses instead of standard AC fuses?
DC circuits are much harder to interrupt than AC circuits because DC current does not have a natural zero-crossing point. PV fuses are uniquely engineered to extinguish high-voltage DC arcs safely and fast.
What certifications do these photovoltaic fuses carry?
Our PV fuses conform strictly to En IEC 60269-1 standards and carry the CE certification, indicating compliance with safety, health, and environmental protection requirements in the European Economic Area.
What does the "TT" fusing speed mean?
The "TT" designation represents a specific, highly responsive timing curve designed to react quickly to overcurrent events, minimizing potential damage to sensitive PV modules and system components.
How should these fuses be packaged for transit?
To prevent any physical damage or moisture ingress during transport, they are packed using safe bubble wrap protective layers inside heavy-duty outer cardboard cartons.
