Applied Range
High Quality Materlals
Red Copper Or Alloy Material
The base contacts are made of high-performance red copper or alloy, which can ensure the base's high conductivity, wear resistance, corrosion resistance and excellent mechanical strength.
Highly resilient steel springs maintain contact pressure during thermal cycling, preventing resistance drift.
Captive Spring Mechanisms
High Performance Nylon Material
The fuse base is made of high temperature resistant nylon,which has excellent mechanical strength, moisture resistance and combustion resistance, and can withstand harsh environments.
Product Details
Excellent Mechanical Strength
It can withstand physical impacts, vibrations,and mechanical stresses, ensuring that the base is not easily deformed or damaged during installation or operation.
Flame resistance
The material has self - extinguishing properties or a high flame - retardant rating, reducing the fire risk and enhancing overall safety.
Optimized Heat Dissipation Design
Combined with an open - type structure, it promotes heat dissipation, reduces temperature rise, and ensures reliable operation under high - current loads.

| Module | Chifeng fuse Holder | Inferior fuse Holder | Performance impact |
| Fusant material | High-performance red copper/alloy (high conductivity, wear/corrosion resistance) | Low-grade brass/iron sheet (poor conductivity, easy oxidation/corrosion/wear) | Affect the fuse accuracy and reaction speed |
| Base body | High-temperature resistant nylon (flame-retardant, self-extinguishing, moisture/combustion resistance) | Ordinary/recycled plastic (low melting point, no flame retardancy, easy deformation/melting) | Affect insulation and arc extinguishing ability |
| Filler quality | High-grade quartz silica,Filling tightly | Ordinary quartz sand or substitute, loosely filled | Affect the arc extinguishing speed |
| Electrode material | Silver-plated copper electrode,low contact resistance | Ordinary metal, easy to oxidize | Affect temperature rise and energy consumption |
| Spring material | Highly resilient steel springs (maintain contact pressure, prevent resistance drift) | Ordinary iron springs (poor elasticity, quick tension loss, causes poor contact) | prevent resistance drift |
| Performance index | Chifeng fuse Holder | Inferior fuse Holder | Potential risk |
| Current-time characteristic | Precise and stable, matching the overload characteristics of the equipment | High dispersibility and instability | Mis-protection or insufficient protection |
| Breaking capacity | High breaking capacity, strong current limiting characteristics | Insufficient breaking capacity, poor current limiting effect | The fault escalates, resulting in system power outage |
| Arc control | Rapid arc extinction (microsecond level) | Slow arc extinction (millisecond level) | Cause a fire or explosion |
| Aging characteristics | Good long-term stability | Severe characteristic drift | Reliability decreases over time of use |
| Consistency | The differences between products are small | Different performance of products from the same batch | The protection effect is unpredictable |

3. Installation & Maintenance Efficiency
Modular DIN-Rail Mounting: Simplifies integration into combiner boxes and inverters (e.g., Onccy's EDFH, CNC's YCF8-PV), reducing installation time by 30% with tool-free clipping .
Tool-Free Fuse Replacement: Rotating carriers (e.g., Mersen HP15FHM32) and bayonet mechanisms enable quick swaps without disassembling equipment, minimizing downtime .
Adjustable Terminals: Accommodate diverse wiring (e.g., 2.5–10 mm² cables), ensuring firm connections and vibration resistance .
4. Application-Specific Innovations
Utility-Scale Solar Farms
High-Current Handling: Supports up to 60A/1500V (Littelfuse SPXV) for string protection, enabling consolidation of inputs to reduce combiner box complexity .
Thermal Management: Ventilated designs (e.g., LFXV15 fuse boxes) dissipate heat efficiently, extending fuse life during sustained high loads .
Residential & Commercial Systems
Compact Form Factors: Slim profiles (e.g., 10×38mm or 14×51mm holders) save panel space while maintaining 30–32A ratings .
DC Arc Suppression: Quartz-sand-filled fuse tubes (Onccy, Zhejiang Galaxy) quench arcs at 6 kV/μs dv/dt, critical for rooftop PV safety .
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.
