The centerpiece of our medium-voltage components - sustainable and maintenance- free! Vacuum interrupters are the centerpiece of our medium-voltage components. The hermetically sealed vacuum contact gap keeps the switching characteristics of the interrupters constant throughout their entire lifecycle. Special contact materials made by Siemens ensure that our vacuum interrupters offer absolutely top performance. With valuable features that include high short-circuit switching capacity and minimum forward resistance, they ensure reliable switching even under difficult environmental conditions – like vibration and fluctuating frequencies – regardless of whether they’re installed horizontally or vertically. Our vacuum interrupters can perform up to 30,000 operating cycles when used in circuit breakers and up to three million for contactors – maintenance-free, throughout their entire service life. • Reliable performance and maintenance-free operation • Innovative vacuum technology for an ecological energy transition • Highly qualified R&D team to support integration in customer gear • Reduced OPEX through minimal resistance, allowing optimized customer design
