Scope of application
NT/NH3 fuse link knife type contact fuse is suitable for AC 50Hz and DC circuits, with rated voltages of AC500V, AC690V, DC250V, DC440V, and rated currents up to 1250A.
NH hrc fuse refers to an electrical device that uses the heat generated by itself to melt and disconnect the circuit when the current exceeds a specified value. A fuse is a type of circuit breaker that, when the current exceeds a specified value for a period of time, melts the molten material with the heat generated by itself, causing the circuit to disconnect; A current protector made using this principle.NT/NH3 fuse link it is used for line overload or short circuit protection in industrial electrical equipment distribution equipment.

Here are some precautions:
working conditions
Normal working conditions and correction parameters
The fuse operates under the following normal usage conditions and does not require additional modifications. When exceeding normal usage conditions, if within the allowable usage range, some parameters may need to be adjusted or consulted. If it exceeds the allowed usage conditions, please consult our company and conduct a job adaptability assessment and testing of the conditions. The recommended long-term current value should not exceed 80% of the rated current.
