Product Advantage
Surge-Resistant Conductive Design for Long-Term Circuit Safety The custom thick elastic copper clamp built into this 690V AC Fuse Holder evenly wraps 10×38 gG ceramic fuse bodies, delivering consistent clamping pressure even under repetitive PV AC surge shocks. It efficiently suppresses abnormal temperature spikes caused by fluctuating solar output loads, eliminating hidden overheating hazards inside cabinets. Meanwhile, the fully enclosed flame-retardant housing of the 32A PV Fuse Holder physically blocks high-temperature short-circuit arcs, stopping arc leakage and lowering fire risks for the whole circuit system of this 690V 32A Fuse Holder.
Full-Range Standardized Safety Compatibility for Retrofit PV Projects This 32A PV Fuse Holder achieves universal safety matching with all 0.5A–32A 10×38 gG AC ceramic fuses, covering the full AC working voltage spectrum up to 690V. The unified DIN rail mounting dimension of the 690V AC Fuse Holder supports one-to-one replacement of outdated fuse bases without cutting or drilling cabinet panels. Avoiding secondary insulation damage during renovation greatly maintains the original safety performance of PV power systems, making the 690V 32A Fuse Holder a reliable safety upgrade solution for aged distributed solar stations.
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.
