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 Iron And Resin
The fuse base is made of high-temperature-resistant resin and iron,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 performance Iron (high strength, high temperature resistance, corrosion resistance, stable structure) | Ordinary/recycled iron sheet (low strength, easy rust/deformation, poor high temperature resistance) | 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 |

Cylindrical Ferrule Type DC Fuses
This type of fuse adopts a cylindrical ceramic shell and ferrule type connection structure, with small size and high space utilization rate. It is mainly used in the protection of battery modules, low-current branch circuits, and auxiliary power supply circuits in ESS, with current specifications usually below 125A.
High-Voltage DC Fuses for Utility-Scale ESS
This type of fuse is designed for ultra-high voltage DC scenarios of large-scale grid-level energy storage stations, with voltage levels up to 3000V DC, breaking capacity up to 100kA DC, and is used for the protection of the main bus of large-scale battery energy storage systems and high-voltage DC transmission links.
In addition, according to the protection function, energy storage fuses can also be divided into full-range breaking fuses (aR category, which can reliably break from the minimum melting current to the rated breaking current) and partial-range breaking fuses (g category, mainly used for short-circuit protection), among which the aR category full-range breaking fast-acting fuses are the absolute mainstream of ESS protection, because they can meet the dual protection needs of overload and short-circuit of ESS.
2. Core Functions of Energy Storage Specialized Fuses in Energy Storage Systems
In the entire ESS architecture, the energy storage fuse is not just a simple overcurrent protection component, but the core cornerstone of the entire system's safety protection system. Its core functions run through the whole process of ESS operation, fault handling, and safety linkage, and are specifically reflected in the following 6 core dimensions:
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.
