More info
The EFEN NH blade fuses with gG characteristic are designed for robust and reliable protection in low-voltage electrical distribution systems. These fuses are known for their high rupturing capacity, generally exceeding 100 kA, ensuring they can handle even the highest short-circuit currents encountered in such environments. These fuses are widely used in various industrial applications, including cable and line protection.
The NH fuse-links are available in sizes ranging from 00 to 4a, with current ratings from 6A to 1600A, providing flexibility for different protection needs. They are designed for use in both AC (up to 690V) and DC (up to 440V) systems, making them versatile for various applications. The gG characteristic ensures full-range breaking capacity, making these fuses ideal for protecting both conductors and equipment against overloads and short circuits.
