1-pole bi-directional DC NO contactors, max. switching voltage up to 1,000 volts and currents up to 3,000 amps
C830 – DC bi-directional switching
Innovative DC contactors engineered for rapid megawatt charging — compact, customer-driven and ready for mobile applications
The C830 series meets the growing demand for high-performance, compact solutions that align with rapid electrification. Handling up to 3,000 amps in a compact design the series supports all kind of e-mobility applications. Engineered for seamless integration, C830 series is optimized for Level 2 and Level 3 megawatt-class charging, accelerating development timelines and reducing system complexity .With built-in energy-saving features, integrated thermal design, and consistent performance under continuous load, the new contactors C830 reduces operational costs without compromising reliability.
Features
- No explosion risk:
Permanent magnetic arc quenching without gas encapsulation to prevent overheating and overpressure at all times - Best-in-class performance:
Silver alloy contact pills with a contact resistance of just μOhm 35 for low power losses and less cooling - High longevity:
Separate contact systems for making and breaking as well as for carrying the current ensure maximum contact protection - High protection:
Breaking capacity up to 15,000 amps for 5 milliseconds without contact welding - Low power consumption:
Integrated economizer for optimal pull-in performance during switch-on and minimizes energy consumption in holding mode - High shock resistance:
60g / 11ms Functional-On, 30g /11 ms Functional-Off - Vibration resistance:
ISO16750-3, Test VII - V2G ready:
Fully bidirectional
Applications
