JUNW NT Series 160A/250A/400A/630A/1250A Fuse Base

1.Core Product & Application
JUNW NT/NH Series blade shaped fuse bases are high-performance low-voltage protection components, engineered for reliable overcurrent and short-circuit protection in power distribution systems. They are ideal for industrial applications, utility facilities, and motor control circuits, delivering stable, long-lasting performance in demanding environments to safeguard power transmission and connected electrical equipment.
2.Premium Material & Structural Advantages
•Base Housing: Crafted from high-temperature resistant nylon, offering excellent mechanical strength, moisture resistance, and flame-retardant (self-extinguishing) properties, withstanding physical impacts, vibrations, and harsh operating conditions.
•Contact System: Contacts are made of high-performance red copper or alloy, ensuring superior conductivity, wear and corrosion resistance. Captive spring mechanisms maintain consistent contact pressure during thermal cycling, eliminating resistance drift.
•Optimized Heat Dissipation: Open-type structure enhances heat dissipation, reducing temperature rise for reliable operation under high-current loads.
