High Current Fuses
Product use:
High voltage current limiting fuse is suitable for indoor AC 50Hz, rated voltage 3.6 ~ 40.5 kv system. It can be used with other protective electric appliances (such as vacuum contactor, load switch, etc.) as short-circuit or overload protection components of power transformer and other electric equipment, it is also a necessary supporting product for high voltage switchgear, ring network cabinet and high and low voltage pre-installed power station.
Features:
1. High breaking ability: rated breaking ability is 31.5 ~ 50kA.
2. Low power consumption: a lower temperature rise, when the fuse is used in fully enclosed insulation device, this feature is more significant.
3. Low arc voltage: low arc voltage in the breaking process.
4. Easy and reliable installation.
5. Product specifications are standardized and widely applicable.
6. It has a great current limiting function, so when choosing the conductor of the protected element, we only need to design according to the limiting current value instead of all the short-circuit current value, which can greatly save the amount of conductive material and other materials.
7. The equipped impactor can be used as the action sign of the fuse and the trigger structure of the load switch and contactor.
Product Technical Standard:
High-voltage current-limiting fuses conform to the national standard GB15166.2-2008(equivalent International Electrotechnical Commission IEC60282-1:2005) , and their external dimensions conform to the British standard BS2692 and German standard DIN43625.
