Vacuum Interrupters

We are well known in the field of Vacuum Interrupters offering environmental friendly medium and high voltage interrupters. These Vacuum Interrupters can reliably switch high stress currents robustly without the need for unreliable cooling or ventilation systems. Vacuum Interrupters provide long life and low maintenance, save space, and reduce costs. Used for repetitive switching, motor in rush current interruption, fault protection, and over current and short circuit protection.

Today about 80 percent of power network operators are in favor of vacuum switching technology. The market share of vacuum circuit-breakers is more than 99% in Germany. The core component of this switching principle is the Vacuum Interrupter. The decisive advantage of the Vacuum Interrupter is that its properties remain constant throughout the entire life cycle, due to the hermetically tight vacuum interrupter which eliminates any external influences.
