| Rated Current (A) | 1-30A | 1-30A |
| Breaking Capacity (kA) | 20kA | 20kA |
| Standards Certification | UL 2579, IEC 60269-6 | UL 2579, IEC 60269-6 |
| Temperature Range | -40°C to +90°C | -40°C to +90°C |
Solar Power Protection PV Fuse FAQ
What is the primary role of a PV fuse in a solar power system?
The primary role of a Solar Power Protection PV Fuse is to provide overcurrent protection for individual strings of solar panels. It acts as a critical safety device that isolates a fault—such as a short circuit—within a single string, preventing damage to the entire array, wiring, and inverters, thereby mitigating fire risk.
How do I select the correct amperage for a PV fuse?
Selecting the correct amperage is crucial. The fuse's rated current should be approximately 1.5 to 1.56 times the module's Short-Circuit Current (Isc) under Standard Test Conditions (STC). This multiplier accounts for potential current surges due to increased irradiance. Always consult your system designer and the National Electrical Code (NEC) for specific requirements.
Can a standard AC fuse be used in a DC solar application?
No, this is extremely dangerous. DC circuits, like solar arrays, present a much greater challenge for arc interruption than AC circuits. A Solar Power Protection PV Fuse is specifically engineered with arc-quenching materials and design features to safely extinguish a DC arc. Using an AC fuse in a DC application can lead to its failure to interrupt a fault, resulting in fire or equipment explosion.
The legacy of market leaders shows that quality and innovation are paramount. At Galaxy Fuse, we don't just follow this standard; we build upon it. Our GX-700 Series PV fuse is engineered with the same precision and commitment to safety, offering you a reliable, high-performance solution for your solar projects.
