Import Bases For Solar Pv Fuse Use — Buy in wholesale FOB from Supplier in China

Cfriend Electric(Kunshan)., Co.Ltd manufactures fuse bases for solar photovoltaic applications, designed to carry 10 mm x 38 mm fuse links in DC string protection circuits. The units conform to IEC 60269-6, GB/T 13539.6, UL 4268-18, and UL 4248-18 standards, with a rated voltage of 1000 V DC and breaking capacity of 33 kA. Current ratings are 30 A under UL and 32 A under IEC, suited to residential and commercial solar installations where overcurrent protection is critical to array safety.

The base housing uses imported engineering plastics selected for flame resistance and thermal stability across the stated -30 degrees C to +120 degrees C operating range. Current-carrying elements are pure copper with silver plating, formed by one-shot stamping to achieve contact resistance of 9 milliohms or less at 20 degrees C. A high-temper spring clamp ensures consistent contact force on the fuse element, while screw terminals feature anti-rotation design to prevent loosening under cyclic thermal load. Finger-safe construction and polarised multipolar connection capability address installer safety and system expandability.

Target buyers are solar EPCs, inverter and combiner box manufacturers, and electrical distributors serving PV markets in North America, Europe, and China. The bases are compatible with standard 10x38 gPV fuse links from major brands. Buyers should confirm whether the supplier provides accessory busbars for multipole assembly, exact terminal torque specifications, and whether UL and IEC certifications are current and cover the specific production site in Kunshan, Jiangsu Province.

specs

Cfriend Electric(Kunshan)., Co.Ltd is located at No. 153 Youyi Road, Zhoushi Town, Kunshan, Suzhou, 215312, Jiangsu Province, China. The company holds a harbor trust tier on the platform, though response rate and average response hours both register at zero, indicating limited tracked buyer communication. No founding year, employee count, revenue figure, or factory floor area appears in the source profile. The Kunshan location places it within the Suzhou industrial corridor, a region dense in electronics and precision component manufacturing.

The listing emphasises engineering material selection and manufacturing process details, imported engineering plastics, pure copper silver-plated stamping, spring clamp design, suggesting an in-house production capability rather than pure trading. However, the buyer should independently verify ISO 9001 or IATF 16949 quality system registration, factory inspection reports, and whether the UL recognitions are active and list the Kunshan facility. No named OEM clients, annual output figures, or export market breakdown are provided in the source.
