Vacuum interrupters are the engineered heart of all Siemens medium‑voltage switchgear. Having pioneered vacuum switching technology in the early 1970s, we design our vacuum interrupters to deliver the best vacuum switching available on the market.

Typical operating performance reaches up to 30.000 cycles in circuit-breakers and up to three million cycles in contactors — maintenance‑free across the whole lifecycle.

For utilities, OEMs and industrial operators who demand uptime, safety and long-term economy, Siemens vacuum interrupters deliver proven German engineering, environmental responsibility, and market‑leading quality — a clear choice when performance and reliability matter most.
