Zhejiang Hongman Electric Technology Co., Ltd. is one of the most reliable manufacturers and suppliers of nt2 ceramic fuse link in China. We are committed to providing high quality customized products made in China with competitive price. Welcome to wholesale bulk cheap nt2 ceramic fuse link from our factory.
Product Introduction
This series of Ceramic HRC Fuse Link is made of integrated high-temperature ceramic housing, which is standard AC 500V/690V NT2 Fuse Link. All models pass EU safety test certification and serve as export-compliant NT2 Fuse Link with CE Certificate. Manufactured strictly in accordance with IEC/HD 60269-2 international standard with gG general protection characteristic, it is widely applied in industrial low voltage distribution, PV energy storage power stations, high-power motor circuits, rectifier and inverter equipment.
The fuse body is filled with high-purity quartz sand for arc extinction, matched with thick Tin-plated pure copper knife blade contacts to achieve low contact resistance and low operating temperature rise. Breaking capacity reaches 120kA at AC500V and 50kA at AC690V, which can instantly cut off large short-circuit current to fully protect downstream cables and electrical equipment. Current ratings range from 125A to 400A, standardized plug-in design matches supporting NT2 fuse base for quick replacement without complete power cut, greatly saving on-site maintenance time. Our factory is equipped with full automatic fuse production line, independently controlling all procedures including element stamping, ceramic tube firing, quartz sand filling and finished aging test. Standard ratings are always in stock, we support bulk purchasing and customized OEM service for overseas switchgear manufacturers and energy storage integrators.

FAQ
Q1: Can this Ceramic HRC Fuse Link be used for both 500V and 690V control cabinets?
A: Yes, this AC 500V/690V NT2 Fuse Link supports dual voltage, it can reach standard breaking protection performance under both voltage working conditions.
Q2: Are all certification documents complete for exporting to Europe?
A: Yes, every shipment is NT2 Fuse Link with CE Certificate, attached with official CE test report and RoHS certificate, which can be directly used for customs clearance and project bidding.
Q3: Do I need to replace the whole base after the NT2 fuse blows?
A: Only replace the fuse link, separate design of fuse and base. The Ceramic HRC Fuse Link is pluggable independently, the base can be reused for a long time to cut maintenance cost.
