Pantographs require the smallest possible mounting space and are connected to the busbar with its characteristic scissors. Main features and advantages: •Vertical disconnection •Busbar connection •Diagonal or parallel arrangement •Applicable for flexible and rigid busbar connections •Compact and stable design allows for high mechanical and thermal loads •Self-interlocking mechanism prevents opening during a short circuit •Sophisticated contact system ensures long service life and requires no maintenance effort •Tested according to national and international standards, such as IEC, ANSI, GOST R and GB Our disconnector and earthing switch technology The technology of our products sets international trends. We continuously ensure our high quality through optimized production processes, constant product development and a certified quality management system. Our contact systems offer the following advantages: •Short circuit conditions increase the contact force •Highest dynamic/thermal stability in the event of leakage current •Optimized for applications with silver plating •Lubrication free solution •Maintenance-free (long term) •Many years of operating experience (+ 40 years) •Our contact system concept is largely based on the original RUHRTAL design Our drive systems offer the following advantages: •Completely finished and pre-adjusted assemblies simplify installation and commissioning •Sturdy, stainless steel housing according to IP 54, standard paint •Can be mounted on switch base on request •IEC tested auxiliary switch with highest endurance class for greatest reliability •Anti-condensation heater
