Vacuum interrupters

The centerpiece of many medium-voltage components is the vacuum interrupter. As a pioneer in vacuum switching technology, Siemens has a comprehensive know-how. Our experience in the manufacturing of more than 5 million units confirm our technological competence. In our production facilities, state-of-the-art machines and production processes are used, whose quality standards and manufacturing precision meet or even exceed the requirements of ISO 9001 and ISO 14001. As a result, we develop and manufacture high-quality products with a long service life, and guarantee a reproducible and consistently high production quality at all times.

  • Constant switching properties throughout the entire lifecycle through hermetically sealed vacuum contact gap, which excludes any external influence

  • High performance thanks to the use of special contact material from own production

  • Up to 30,000 operating cycles for circuit-breakers

  • Up to 3 million operating cycles for contactors

  • Maintenance-free throughout the entire lifecycle

  • Very high short-circuit breaking capacity

  • Minimum contact resistance

  • Reliable functioning under difficult ambient conditions, e.g. vibration, fluctuating frequencies, and for horizontal or vertical installation
