Battery fuse links are critical components designed to protect battery storage systems from short circuits and overcurrents. These fuse links are specifically engineered to handle the unique demands of battery systems, ensuring the safety and reliability of these increasingly vital energy storage solutions. Battery fuse links are essential for preventing damage to the batteries and the connected equipment in case of a fault.

General Specifications:

• Breaking Capacity: High breaking capacity suitable for battery protection.
• Time-Current Characteristics: Fuse-links have a steep characteristic, ensuring fast interruption of short circuit currents (within 5 seconds).
• Power Dissipation: Low power dissipation at nominal current and at 0.7 times the nominal current.
• Pre-arcing Joule integral: This value is given for each fuse type, which indicates the amount of energy the fuse element can handle before it starts to melt.
• Operating Joule integral: This value indicates the total energy the fuse can handle before it breaks the circuit.

Specific Series Information:

• NH00C and NH00: These sizes are available for 80V d.c. applications.
• NH1C and NH1: These sizes are available for 440V d.c. applications.
• NH00: Available for 550V d.c. applications.
• NH1, NH2, and NH3: These are available for 550V, 700V, and 800V d.c. applications, with a specific 3L version for 800V d.c..
• NH gBat XL: Designed for 1500V d.c. applications.

Additional Information:

• Fuse Selection: The operating point must be in adequate distance below the curve, and the short-circuit point must be above the range of tolerance of the curve.
• Power Dissipation: When choosing a fuse switch disconnector, the fuse-link power dissipation must be considered. The power dissipation at the maximal operating current (Pd(IB)) can be calculated using the formula: Pd(IB)=(IB/In)2 x Pd(In).
• Parallel Connection: For increasing the rated current, fuse-links can be connected in parallel, but specific rules apply. The fuse-links must be the same type, size and rating and the current rating is lower than the sum of the single fuse-links.
• Temperature Influence: Ambient temperature affects the rated current, and a temperature derating factor should be applied.
• Indicators: Some fuse links come with standard and striker indicators.
