Applied Range
High Quality Materlals
High Purity Copper Material
The fuse element made of high purity copper metal material has the advantages of high electrical conductivity, good stability, low power consumption and low temperature rise.
The arc-extinguishing medium of the fuse is high-grade quartz silica. The advantage of this material is that it can extinguish the arc generated during the operation of the fuse, providing better heat resistance and higher arc discharge resistance.
High Grade Quartz Sand
High Performance Ceramics
The fuse body is made of high- performance ceramics, which has theadvantages of high temperature resistance, high insulation, high mechanical strength, and chemical inertness.
Product Details
Low Power Consumption And Low Temperature Rise
It can withstand physical impacts, vibrations,and mechanical stresses, ensuring that the base is not easily deformed or damaged during installation or operation.
High Short-Circuit Breaking Capacity
Interrupt currents up to 40 kA.
Robust Construction
Durable ceramic/epoxy housings and weather-resistant designs ensure longevity in harsh environments.

Premium High-Voltage Fuse Solutions: Uncompromising Safety, Unmatched Reliability for Critical Power Systems
In today's increasingly complex and power-hungry industrial, commercial, and utility landscapes, the reliability of electrical protection systems is non-negotiable. High-voltage fuses stand as the first line of defense against catastrophic overcurrent, short-circuit, and overload events, safeguarding expensive equipment, preventing costly downtime, and protecting personnel from life-threatening hazards. Yet, not all fuses are created equal. Inferior, low-quality fuses often masquerade as cost-effective solutions, but they carry hidden risks that can lead to system failures, fire hazards, and irreversible financial losses. At Chifeng, we engineer high-voltage fuses that redefine industry standards, combining premium materials, precision manufacturing, and rigorous testing to deliver protection you can trust, even in the most demanding operating conditions.
FAQ
Q:Do aM NH type fuses have to be marked with green color?
A:Yes, according to IEC 60269-2, the color of aM fuses should be green.
Q:Are dual-indicating NH fuses mandatory or optional?
A:Dual indicator system is optional for NH fuse.
Q:What does NH mean?
A:NH is the German abbreviation, N means low pressure, H means high breaking capacity.
