NH3, AC 500/690V gG/gL RT16-3 Fuse Link, Hrc Ceramic Knife Blade 315-630A

NH3 fuse links are a vital component of the NH fuse system, known as "Low-Voltage High-Performance Fuse". Widely utilized in industrial electrical settings, particularly in Europe, the NH fuse system encompasses a range of sizes, with NH3 being one of the larger sizes denoted by the "3".

Key attributes of an NH3 fuse link include:

1. Physical Size: The "3" signifies standardized physical dimensions, ensuring compatibility with appropriate fuse holders and switchgear designed for this size.

2. Electrical Ratings: NH3 fuse links are characterized by specific voltage and current ratings, defining their maximum voltage handling capacity and the maximum current they can safely interrupt without damage.

3. Protection Mechanism: NH3 fuse links play a crucial role in providing overcurrent protection by interrupting the circuit when the current exceeds a predetermined limit due to overload or a short circuit, thereby safeguarding other components in the circuit.

4. Design: Typically, NH3 fuses feature a knife-blade design with conducting blades at both ends, facilitating easy insertion and removal from their mountings.

5. Applications: These fuses are employed in heavy-duty industrial settings to protect equipment such as motors, transformers, and electrical installations requiring higher capacity electrical protection.

NH3 fuse links are essential for upholding electrical safety in industrial environments, offering dependable protection against excessive currents that could potentially cause damage or hazards.
