　HSF series DC high-speeds fuse is focus on DC protection and have good performance .Xi’an Xilian has launch this new kinds of good quality products at Year 2021.HSF series fuses use new design more cost-effective advantages Ag-Cu fuse-element. This makes our fuses cheaper and economic .HSF series fuses also use Al2O3 ceramic fuse-tube, This cause our fuse have excellent high strength and heat resistance performance. HSF series fuses good at low temperature rise, low watt lose, And optimize low I2t. HSF series DC fuses have the breaking capacity to 250KA at L/R=1-4ms.According to EN60269 standard testing I1,I2,I2a,Breaking capacity to 100KA at L/R=15-30ms.

• Xi’an Xilian have always develop and improve the fuse breaking-capacity.HSF series fuse DC interrupting rating IR up to 100KA.Some of DC interrupting rating IR can be 200-250KA.
• HSF series application ultra fast-acting fuse element design. The clear arcing I2t is lower. DC Arcing extinguish speed is 4-6 millisecond. some kinds of special customized can control to 200-300 microseconds.
• HSF Series have CCC certification and CE certification. And ROHS Certification. Xi’an Xilian has long history cooperation with China famous electrical testing institute.Shanghai Ellectrical Apparatus Research Institute(SEARI) and Suzhou Electrical Apparatus Science Research Institute Co., Ltd (EETI)
• HSF Series products have rich in structure and AMPS. And even in economic price. If customers needs,we can customize the design.(Min QTY 500pcs)  
• Xi’an Xilian has cooperation with Fedex,DHL,UPS. Our products can ship to global by air and ocean.
