DC Solar Fuse | Protectio 1500V, Triplicationes Irritae Minus 37%

Zhnyu Electric's Dc Solar Fuse production begins with strict incoming material control. High-purity silver strip is punched and formed into precise element geometries, while ceramic tube housings are inspected for dielectric strength above 6 kV. Automated assembly lines, part of our 100+ production equipment units, weld end caps and fill arc-quenching sand under controlled humidity to prevent moisture ingress. Every fuse undergoes 100% routine testing: resistance measurement, time-current verification, and DC breaking capacity tests at 1000 V and 1500 V. Batch samples are further validated to IEC 60269-6 and UL 2579, ensuring reliable interruption of DC arcs that behave very differently from AC faults. The finished Dc Solar Fuse is laser-marked with rating, voltage, and traceability codes, then packed in anti-static trays for global shipping. From our 10,000+ square meter facility, we serve photovoltaic, power distribution, and industrial control markets in more than 60 export countries, supported by ISO 9001, CCC, CE, and RoHS certifications plus a metering production license. In a 50 MW Middle East plant, 10,000+ fuses were installed across combiner boxes, and post-commissioning audits showed zero premature failures after 12 months.
