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

1. Core Upgraded Product & Application
JUNW upgraded NT/NH series blade-type fuse bases are high-efficiency low-voltage overcurrent and short-circuit protection devices, with a key optimization of newly added wiring terminals on the fuse base for direct, hassle-free installation. This upgraded design greatly simplifies user wiring and assembly operations, making it perfectly suitable for power distribution systems, industrial equipment, power utility stations and motor control circuits. It provides stable, long-duration protection for power transmission and supporting electrical equipment even in harsh working conditions.
2. Upgraded Structure & Premium Performance Advantages
Newly Added Wiring Terminals: The fuse base is equipped with special wiring terminals, allowing users to complete wiring and installation directly without additional connectors, greatly improving on-site construction efficiency and convenience.
High-Performance Base Material: Made of high-temperature resistant nylon, the base owns outstanding mechanical strength, moisture resistance and flame-retardant (self-extinguishing) performance, resisting physical collision, vibration and severe working environments.
High-Quality Contact System: Constructed with high-grade red copper and alloy contacts, it ensures excellent electrical conductivity, wear resistance and corrosion resistance. The stable spring structure keeps constant contact pressure during thermal cycling to avoid resistance abnormalities.
Efficient Heat Dissipation: Open structural design strengthens heat dissipation effect, reduces temperature rise and ensures stable operation under high-current working conditions.
