JUNW NT Series Blade Shaped Fuse Core

JUNW NT Series Blade-Shaped Fuse Cores
1.Core Product Overview & Compliance
JUNW NT Series blade-shaped fuse links are high-performance low-voltage protection components, fully compliant with international IEC standards. Designed for reliable overcurrent and short-circuit protection in power distribution systems, they feature a universal 500V AC rated voltage and an industry-leading 120kA breaking capacity, ensuring safe and rapid isolation of extreme fault currents to safeguard electrical equipment and distribution lines.
2.Key Advantages of Blade-Type Design
The precision-engineered blade structure delivers ultra-low contact resistance and high electrical conductivity, reducing power loss and temperature rise during operation. Manufactured with reliable copper alloy fuse elements and flame-retardant insulating housings, these fuse links offer good thermal stability, mechanical strength, and corrosion resistance, making them ideal for heavy-load, high-frequency industrial applications and long-term stable operation.
