Mersen S085622

The DIN 43625 fuse serves as an essential component for the protection of high-voltage motors, adhering to the IEC 60644 standard. With a rated voltage of 7.2 kV and an ampere rating of 315 A, this fuse-link is specially engineered to safeguard against short circuit currents and to accommodate repeated peak currents during motor startups.

Constructed from high-quality materials, the fuse elements are made of pure silver, while the caps utilize silver-plated brass, and the body consists of melamine fiber glass. The coefficient K, as defined by the IEC 60644 standard, is noted to be 0.51. This fuse is designed to operate effectively with a maximum breaking capacity of 50 kA and a minimum interrupting rating of 1900 A.

Furthermore, the fuse's clearing I₂T at rated voltage is 2000 kA²s, with a power dissipation of 60 W at 0.7 In. Its cylindrical connection terminal is designed for easy mounting with a clip, ensuring reliable performance in high-voltage switchgear and control applications. This product falls under the Limitor® line of backup fuses, which spans from 3.6kV to 12kV.
