Product Introduction
Our NT3 Ceramic Fuse Link High-Performance Industrial Protection NT3 630A Fuse Link is a high breaking capacity knife-type HRC fuse specially designed for industrial low-voltage power distribution. It adopts high-strength heat-resistant ceramic tube to encapsulate copper variable cross-section melt, filled with high-purity quartz sand inside for rapid arc extinction, providing dual protection against overload and short circuit for 630A high-power loads.
Compatible with AC500V/690V low-voltage switchgear, motor control cabinets and photovoltaic energy storage equipment, it complies with IEC60269 and GB/T13539 standards. With a rated breaking capacity up to 120kA, the plug-in blade design features easy installation, ultra-low contact resistance and stable temperature rise during long-term operation.
We have specialized in electrical protection components for over 10 years, with products sold to industrial markets across Europe, America and Southeast Asia. All items pass strict factory inspection, bulk customization is available, and we aim to be your reliable long-term partner from China.
