Product Advantage
1 Dual Signal Output Structure: Real-Time Remote Monitoring for Smart PV Stations
This premium 800V AC Fuse comes with built-in dual signal transmission module, capable of uploading both circuit on-off position signal and fuse blowout alarm signal to PLC, SCADA and cloud monitoring platforms synchronously. Different from ordinary Solar Fuse Link only equipped with local visual indicator, it realizes unmanned intelligent early warning for medium & large photovoltaic power plants. Once overload, short-circuit or reverse current faults happen, the Solar Fuse Link triggers two-way signal feedback instantly, allowing operation teams to pinpoint faulty PV strings remotely without on-site patrol inspection. The intelligent signal design greatly reduces manual inspection labor and avoids unnecessary full DC array power cut, making this 800V AC Fuse the top high-end selection for smart centralized PV projects.
2 Premium Explosion-Proof Ceramic Core, Stable Long-Term High-Load Operation
Manufactured with high-density high-temperature sintered ceramic tube, this high-grade Solar Fuse Link fully complies with strict IEC 60269-6 photovoltaic safety standard, specially optimized for long fluctuating DC output of solar panels. The thickened explosion-proof shell of the 800V AC Fuse strongly suppresses sustained DC arc expansion and arc leakage inside sealed compact combiner boxes. Adopting integrated tin-plated copper end caps plus oxygen-free pure copper melt, this Solar Fuse Link maintains ultra-low contact resistance under continuous full load up to 125A, zero performance attenuation or thermal aging after years of round-the-clock operation. Superior raw material and precision firing process endow the 800V AC Fuse outstanding anti-aging and explosion-proof performance, far exceeding basic industrial standard requirements for conventional fuses.
3 Integrated Visual Indicator + Remote Signal Dual Protection, Minimize PV Downtime
This high-end Solar Fuse Link combines pop-up visible blowout marker and digital signal transmission function into one unit, building dual-layer fault identification system for PV DC cabinets. For on-site maintenance workers, the prominent pop-up indicator of the 800V AC Fuse supports quick visual fault location without extra testing tools; for back-end intelligent control system, the dedicated signal interface of this Solar Fuse Link sends real-time fault alerts automatically. This dual-mode design perfectly matches high-density miniaturized PV combiner boxes used in large-scale solar farms, solving the core pain point of delayed fault response for ordinary fuses lacking remote signal output, greatly improving overall operation efficiency of the whole PV station.
Production Process & Quality Control System
Ceramic Shell Forming The ceramic body is formed through high-temperature sintering to deliver reliable insulation and explosion-proof performance.
Copper Contact Machining Integrally stamped thickened solid copper blades are electroplated with copper-tin alloy for anti-oxidation, effectively reducing contact resistance.
Fuse Element Assembly Precision fuse strips are fitted with high-purity quartz sand (99% silicon content) to achieve rapid arc extinction.
Finished Product Testing Every single unit undergoes individual testing for breaking capacity, temperature rise and overload fusing performance.
Aging Sampling Inspection Long-term operation under rated current is simulated to eliminate potential overheating risks.
Full-process traceable quality control ensures consistent performance of every fuse link.
