Applied Range
High Quality Materlals
Silver/Silver Copper Alloy Design
The fuse element made of high purity Silver or Silver Copper alloy 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.

2.1 Core Short-Circuit Fault Protection, Suppress Thermal Runaway at the Source
Short-circuit fault is the most dangerous fault type in ESS, which is mainly caused by battery internal defects, insulation damage, improper operation, and external mechanical impact. Once a short circuit occurs, the fault current will rise to tens of kA in an instant, and the huge short-circuit energy will cause the battery temperature to rise rapidly, triggering the decomposition of the battery electrolyte, the release of combustible gas, and eventually leading to thermal runaway, fire and explosion.
The core function of the high-quality energy storage fuse is to cut off the short-circuit fault at the source before the battery enters thermal runaway. The aR category fast-acting fuse can complete the entire process of melting, arc extinguishing and breaking within 100 microseconds, and its unique current-limiting characteristic can cut off the fault current before it rises to the peak value, greatly reducing the let-through energy (I²t) of the fault. Compared with inferior fuses that take milliseconds to complete breaking, high-quality energy storage fuses can reduce the let-through energy by more than 90%, which can completely avoid the battery from receiving excessive short-circuit energy, and fundamentally prevent the occurrence of thermal runaway.
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.
