Sustainability is of utmost importance to us!
As a long time former developer and manufacturer of SF6-free medium-voltage switchgears, we have a wealth of experience in project planning and the implementation of sustainable solutions.
ECOS-C – the SF6-free medium-voltage switchgear
As the slimmest compact circuit breaker in its class, the ECOS-C offers you an SF6-free and user-friendly solution. All panels are equipped with high-quality, vacuum tube circuit breakers and automatic circuit reclosers (ACRs).
The type-tested, metal-encapsulated single busbar system is suitable for a wide range of applications and demanding requirements. “Made in Germany by Driescher” since 2018.
The heavy-duty system for rated voltages up to 24 kV and rated currents up to 630 A is available in 2 to 7-field designs. Individual blocks can be lined up as required by using a simple busbar tap.
