Disclaimer
Fuses described in this document were developed to take over safety relevant functions as a part of a machine or complete installation. A safety relevant system usually contains signaling devices sensors, evaluation units and concepts for safe disconnection. The guarantee and responsibility of correct overall function lies with the manufacturer of the installation or machine. Itʻs beyond SIBA and their sales offices (in the following “SIBA”) to guarantee all features of a complete installation or machine, which was not designed by SIBA. Once a product has been selected, it should be tested by the user in all possible applications. SIBA will not accept any liability for recommendations, which are given, or respectively implied, by the present description. Due to the description no guarantee, warranty or liability claims can be derived beyond the general SIBA delivery terms.

2 General Design Applications General Design
SIBA HV Fuses are constructed with parallel connected pure silver fuse elements. The design and methods of production of the elements ensure narrow tolerances of 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 end caps are fitted inside the silver plated copper end caps by spot welding. The copper end caps are press fitted onto the porcelain which are glazed inside and outside. The end caps are mechanically fixed to the tube made of a high grade technical ceramic tube, and additionally sealed with a durable elastic sealing medium. This method has been proven over many decades of positive field experience and ensures tightness against ingress of water vapor.
Applications
High Voltage fuses (HV fuses) are used as protection devices in medium voltage switchgear. The great advantage is the very fast current-limiting operation in the event of short-circuit failures, consequently, protecting the switchgear and equipment against dynamic thermal effects of such short-circuits in a very effective way.
SIBA HV fuses can be used for the protection of:
