The Siemens 3NA3340 is a high-quality low voltage high rupturing capacity (LV HRC) fuse link designed to provide reliable overcurrent protection in industrial settings. This part is a size 3, NH3 class fuse link with a rated current of 200 A, suitable for both AC and DC applications. It is rated for use at 500 V AC and 440 V DC, ensuring versatility across different electrical systems.
Crafted with non-insulated grip lugs and a front indicator, the 3NA3340 allows for easy installation and immediate status recognition. The operating class of the fuse link is gG, indicating it is designed for general applications and capable of protecting both cables and equipment against short circuits and overloads.
The fuse link features a robust design with blade contacts that are non-corroding and silver-plated, enhancing conductivity and resistance to environmental factors. The product is also designed to be mounted in any position, with a vertical orientation preferred for optimal performance.
With a switching capacity current of 120 kA according to IEC 60947-2 standards, the Siemens 3NA3340 is capable of interrupting high fault currents, ensuring the safety and integrity of electrical circuits. The part's power loss is rated at 14.9 W per pole, which is a consideration for thermal management in electrical enclosures.
The 3NA3340 operates within an ambient temperature range of -5 °C to 40 °C, making it suitable for a wide range of environmental conditions. It also has an IP20 protection class rating with connected conductors, signifying protection against solid objects larger than 12.5 mm but not against liquids.
This LV HRC fuse link is an essential component for industrial electrical protection, offering reliability and safety in a compact, efficient package. Its design and construction are in line with Siemens' commitment to quality and performance in electrical protection technologies.
