They are intended for protection of electric motors and devices against short circuit currents. In the overload range adittional protection is necessary. Fuse - links are produced in sizes 00, 0, 1, 2 and 3. Fuse - links with reduced dimensions exist by smaller rated currents - reduced sizes 00C, 1C, 2C and 3C. We offer them in two basic types : s NON INSULATED TYPE WITH INDICATOR ON THE TOP COVER PLATE type NVO s NON INSULATED TYPE WITH INDICATOR IN THE MIDDLE OF CERAMIC BODY type 3NVO.
