3NA3354-6

The Siemens 3NA3354-6 fuse element serves as a critical component in electrical systems, providing essential protection. It operates efficiently with an operational current of 355 A and can handle supply voltages of up to 690 V. The device has a compact design, with a width measurement of 71.2 mm and a total weight of 1037 g. Its mounting type consists of non-insulation grip lugs, which facilitate easy installation in electrical panels or systems. The fuse exhibits a protection class rating of IP20. This rating indicates its suitability for indoor use, safeguarding against solid objects, while not being ideal for direct exposure to water.

Designed to handle significant electrical loads, the fuse offers impressive breaking capacities of 120 kA for AC circuits and 25 kA for DC circuits, allowing it to interrupt high fault currents effectively. Power loss during operation is noted at 32.5 W, which is acceptable for this type of component. The operational and storage humidity limits are set at a maximum of 80% non-condensing, which ensures optimal performance in most conditions. Additionally, the fuse element is capable of functioning at altitudes up to 1000 meters above sea level, making it adaptable for various installation environments, including high-altitude locations.
