Product catalog summary
Company Overview: The document is a 2008 catalogue from SIBA, a company specializing in fuses and switchgear. It provides contact information for various international offices, including locations in Austria, China, Czech Republic, Denmark, Netherlands, Poland, Russia, South Africa, Southeast Asia, United Kingdom, and the United States.
Product Specifications: The catalogue includes detailed specifications for SSK-type fuses, which are used for transformer protection in electrical circuits. Key parameters include rated current, rated breaking current, minimal breaking current, pre-arcing I2t-value, total I2t-value, and power loss. The document also provides dimensions such as length and diameter for different fuse models.
Technical Features: SSK-type fuses are highlighted for their efficiency in transformer protection, offering an alternative to circuit breakers. They are designed to limit short-circuit power early in the process and can be adapted for installations over 630 kVA. The coordination between HV fuse-link and switch-disconnector is specified in IEC 62271-105.
Applications and Benefits: SIBA's SSK-type fuses are particularly suited for the wind energy sector, where high demands are placed on electrical installations. The fuses are designed for transformer powers up to 3,150 kVA. The document emphasizes the cost-saving benefits of using SSK-type fuses over traditional circuit breakers.
Research and Development: SIBA is committed to intensive research and development, particularly in addressing the heating of fuses. Long-term test series and empirical work ensure the continuous improvement of the SSK production series to meet future demands for regenerative energies.
