Fuse link - NH2 gBat 400A/550V DC - for battery protection, energy storage / DC 004724267

DC Installation Safety – NH2 gBat Fuse Links

NH2 gBat fuse links are reliable components designed to protect direct current (DC) circuits, particularly batteries and energy storage systems. They provide effective protection against overload and short circuits, minimizing the risk of damage and downtime in the system. The design and characteristics of these fuse links have been optimized for the specific requirements of DC applications, where inrush currents and arc characteristics differ from AC circuits.

Characteristics and Application

NH2 gBat 400A/550V DC fuse links are characterized by a fast response to overvoltages, which is crucial in uninterruptible power supply systems and renewable energy sources. The gBat characteristic ensures optimal selectivity and coordination with other protective elements in the installation. A wide range of rated voltages (up to 550V DC) makes them a universal solution for various applications. Application in protecting DC battery systems is the main specialization of this type of fuse link, but they will also work well in other DC installations requiring high reliability.

Key Features and Benefits

• Rated current 400A: Provides protection for circuits with high current draw, typical of battery systems and energy storage.
• Rated voltage 550V DC: Compatibility with a wide range of DC installations.
• gBat characteristic: Fast response to overvoltages, ensuring effective protection of components sensitive to sudden voltage changes.
• Top indicator: Allows for quick visual identification of a blown fuse link, making it easier to locate and repair faults.
• Short-circuit interrupting capacity 30kA: High short-circuit interrupting capacity guarantees the safety of the installation even in the event of serious disturbances.
• No metallic insulated grips (IMGL): Increases safety and minimizes the risk of accidental contact with live parts.
• Compliant with IEC 60269-7 standard: Confirmation of meeting stringent safety and quality standards.

Additional information: The weight of a single fuse link is approximately 700g, and the basic packaging contains 3 pieces (weight 2.05kg). The transport packaging holds 24 pieces (weight 17.8kg).
