The Siemens 3NA3254 is a high-quality HRC (High Rupturing Capacity) fuse element designed to provide reliable overcurrent protection in industrial settings. This component is part of the SENTRON product family, known for its robustness and efficiency in safeguarding electrical circuits.
With a nominal current rating of 355 A, the 3NA3254 is capable of handling significant electrical loads, making it suitable for a wide range of applications. The fuse operates effectively within a supply voltage range of up to 500 V AC and 440 V DC, ensuring versatility across different power systems.
The fuse link features a gG operating class, which indicates it is designed for general application and is capable of providing both short-circuit and overload protection. This characteristic makes it an excellent choice for protecting cables and power lines, as it can interrupt fault currents up to 120 kA according to IEC 60947-2 standards.
The 3NA3254 is engineered with blade contacts and front indicators for ease of use and quick identification of fuse status. Its non-corroding, silver-plated switching contacts are built to maintain integrity over time, ensuring long-lasting performance.
With a power loss rating of 26 W, the fuse operates efficiently, minimising energy waste and heat generation. The mechanical design allows for flexible installation, with the ability to mount the fuse in any position, though a vertical orientation is preferred for optimal performance.
The compact dimensions of 70.5 x 57 x 147.6 mm and a net weight of 654 g make this fuse element a practical choice for space-constrained environments. Its IP20 protection class with connected conductors ensures that the fuse is safeguarded against the ingress of solid objects, adding to its durability and reliability in industrial applications.
Overall, the Siemens 3NA3254 HRC fuse element is a dependable and efficient solution for protecting electrical equipment from overcurrents, ensuring the safety and continuity of electrical systems in commercial and industrial facilities.
