NH2 fuse link is a standardized component within the NH fuse system, specifically classified as a mid-range size within the NH series, which ranges from NH000 to NH4.
Key characteristics of an NH2 fuse link include:
1. Physical Size: The "2" designation denotes the standardized physical size and dimensions of the fuse, ensuring compatibility with corresponding fuse holders and switchgear.
2. Electrical Ratings: NH2 fuse links are defined by their rated voltage and current, indicating their electrical handling capabilities. These fuses are designed to carry a specific amount of current continuously and to interrupt overcurrent in the event of a fault.
3. Protection: NH2 fuse links serve the primary purpose of safeguarding electrical circuits from overcurrent resulting from overloads or short circuits. When an overcurrent occurs, the fusible element inside the fuse melts, breaking the circuit and preventing potential damage to the electrical system.
4. Design: NH2 fuses commonly feature a knife-blade design with contact blades at both ends, enabling easy insertion into and removal from fuse bases or disconnect switches.
5. Applications: They are frequently utilized in various industrial applications, such as motor protection, distribution boards, and control systems, where robust overcurrent protection is essential.
6. Identification: The fuses are clearly marked with their rated current and breaking capacity, allowing users to select the appropriate fuse link for their specific electrical application.
NH2 fuse links are crucial components in ensuring electrical safety, providing reliable protection against overcurrent in industrial environments.
