Long blade version
Square body semiconductor fuse type, SQB are available in4 different body sizes. Each size is available in various mounting styles, body sizes, and amp ratings to allow the greatest flexibility in equipment design. SQB fuses provide superior performance for the protection of today's power semiconductors. The use of silicated sand as the quenching medium together with special shape and form of the pure silver melting elements gives excellent results of low I2t current interrupting ratings. The elements are welded to the contacts and provide extended life under high cycling load conditions. Fuses are available to be fitted with micro switches.

High Voltage Fuses

German DIN standard for air and gas insulated switchgear and outdoor switchgear. High voltage Fuse-links have parallel connected pure silver fuse-elements. The design and methods of production of the elements ensures narrow tolerances of the time-current characteristics. The fuse elements are wound on a ceramic support and are attached to the silver plated connection caps by means of spot-welding.

The connection caps are fitted inside the silver plated copper end caps by spot welding. The copper end caps themselves are press-fitted onto the porcelain tube, which is glazed inside and outside. The end caps are furthermore mechanically fixed to the porcelain tube and additionally sealed by a durable elastimer sealing medium. This sealing method has been proven over many decades of positive field experience and ensures tightness against ingress of humidity. Inquires for fuse high voltage custom applications are welcome.
