1-pole bi-directional DC NO contactors, max. switching voltage up to 1,500 volts and currents up to 1,500 amps
C305 – DC bi-directional switching
Innovative DC contactors engineered for rapid megawatt charging — compact, customer-driven and ready for stationary applications
Handling up to 1,500 amps, the C305 series is a compact high-performance contactor to cover MCS Level 2. With built-in energy-saving features, integrated thermal design, and consistent performance under continuous load, the new C305 contactors 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 50 for low power losses and less cooling - High protection:
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 bidirectional
Applications
Stationary use such as charging stations, energy storage, photo voltaik
