1-pole bi-directional DC NO contactors, max. switching voltage up to 1,500 volts and currents up to 1,500 amps
C805 – DC bi-directional switching
Innovative DC contactors engineered for rapid megawatt charging — compact, customer-driven and ready for mobile applications
C805
The C805 series meets the growing demand for high-performance, compact solutions that align with rapid electrification. Engineered for seamless integration and by handling up to 1,500 amps C805 contactors are optimized for Level 2 megawatt-class charging, accelerating development timelines and reducing system complexity.
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 50 for low power losses and less cooling - High protection:
High breaking capacity up to 10,000 amps for 20 milliseconds without contact welding - Low power consumption:
Integrated economizer for optimal pull-in performance during switch-on and minimizes energy consumption in holding mode - V2G ready:
Fully bi-directional (V2G ready)
Applications
Mobile use such as commercial vehicles, busses, off road, passenger cars
