Mersen DC offers provide a very high performant protection for railway power and auxiliary circuits. Mersen DC Semiconductor fuse-links were developed to provide improved performance required by todays new DC equipment. These fuse-links are typically operated at more elevated temperature than other fuse type, have lower I²t to minimize damage to protected components on short circuits, lower watts loss and longer life.
"""Mersen HV fuse-links have been used for reliable protection in high-voltage switchgear and controlgear and high-voltage systems for decades.Mersen HV fuse link for motor protection is specially designed to protect HV motors against the effect of short circuit current and support repeated peak currents due motor starting.Mersen uses the best materials : fuse elements are in pure silver, caps are in silver-plated brass and body is in melamine fiber glass.As defined in the IEC 60644 the coefficient K is 0.51."""
