Product Advantage
As standard 10x38mm 32A Fuse, it matches mainstream 1000V solar combiner layouts. Once reverse current or short-circuit fault occurs, the pop-up marker pops out visibly without full DC bus shutdown. Optimized for fluctuating PV DC output, this 1000V DC 32A Fuse keeps ultra-low temperature rise under continuous rated load, and high-temperature sintered ceramic tube restrains persistent DC arc leakage inside sealed cabinet spaces.
Stable DC Protection of 1000V DC 32A Fuse 20kA DC breaking capacity can instantaneously cut reverse surge current generated by mismatched PV panels, effectively avoiding module and inverter burnout. The pure copper melt maintains stable performance under long-term variable DC loads.
Production Process & Quality Control System
High-Temperature Ceramic Tube Sintering Raw ceramic blanks are fired at 1180℃ high temperature to form integrated explosion-proof tube housing with outstanding insulation and DC arc resistance, fully complying with IEC gPV environmental working requirements.
Precision Pure Copper Melt Machining Variable cross-section pure copper strips are stamped and calibrated strictly to match standard gPV time-current tripping curve, guaranteeing consistent overload & short-circuit response for every 1000V PV Fuse Link.
DC-Specific Quartz Sand Filling & Hermetic Sealing 99% high-purity arc-extinguishing silica sand is evenly filled into each tube, then fully sealed to eliminate air gaps, realizing millisecond-level DC arc extinction for the 10x38mm 32A Fuse.
Pop-Up Mechanical Indicator Assembly Elastic trip marker components are mounted inside the ceramic tube, ensuring clear, stable pop-up alarm after fuse blowing for all 1000V DC 32A Fuse units.
100% Single Finished Product Performance Test Each individual fuse undergoes independent testing covering DC breaking capacity, continuous temperature rise, indicator ejection reliability and sealing tightness; defective products are directly scrapped without flowing to next procedure.
Long-Term Aging Sampling Inspection Random sampling is taken for 24-hour full-rated DC current endurance test under simulated cabinet high temperature, eliminating potential overheating and premature melting risks.
Full-Batch Traceability Management Complete production records, raw material inspection reports and finished test data are archived per batch. All files are available for third-party factory audit, overseas tender review and after-sales quality tracing of the 1000V PV Fuse Link.

FAQ
Q1: How much current derating is required when this 1000V PV Fuse Link works at 3000m altitude?
A1: Per IEC rule, current derate 0.5% per 100m above 2000m. For this 1000V DC 32A Fuse, the max working current at 3000m altitude is 30.4A to avoid overheating risk.
Q2: Can the 10x38mm 32A Fuse work inside outdoor waterproof PV combiner boxes?
A2: Yes. High-temperature & moisture resistant ceramic housing fits sealed outdoor cabinets. Avoid direct rain splash during installation to extend service life of this 1000V PV Fuse Link.
Q3: How to adjust rated current when cabinet ambient temperature exceeds 40℃?
A3: Follow Kt temperature correction curve. Operating current of the 1000V DC 32A Fuse must be reduced correspondingly above 40℃ to prevent premature melting of pure copper melt.
Q4: What pollution & installation class does this 10x38mm 32A Fuse comply with?
A4: Pollution grade 3, installation category III, suitable for most industrial PV power distribution environments within -40℃ ~ +60℃ ambient temperature range.
