Structural Features:

RT Type: RT series fuses may have various structural forms, such as knife-shaped contacts and wedge-shaped bases, with insert-type structures being the most common.

 

NT Type: Although the specific structure of NT type fuses may vary depending on the model, they generally follow the design principles and technical specifications introduced from the German company AEG.

 

Performance and Applications:

RT Type: RT series fuses are typically used for low-voltage circuit protection, featuring a wide rated current range and stable fusing characteristics, suitable for various industrial and commercial applications.

 

NT Type: NT series fuses are also suitable for low-voltage circuit protection, but because their technology originates from the German company AEG, some performance parameters may differ to meet the needs of specific application scenarios.
