1-pole bi-directional DC NO contactors, max. switching voltage up to 1,000 volts and currents up to 3,000 amps
C330 – DC bi-directional switching
Innovative DC contactors engineered for rapid megawatt charging — compact, customer-driven and ready for stationary applications
C330
C330 is the first ever compact high-performance contactor to cover MCS Level 2 (1,500) and MCS Level 3 (3,000 A). The series features a compact, open-isolation concept which prevents rupture even under the heaviest failure conditions and heavy short-circuit currents, preventing damage to surrounding components. The C330 contactor can withstand a short-time current of 15,000A for five milliseconds without the contacts welding, significantly enhancing system safety. With separate contact systems for switching and current carrying, the series stands out for its exceptional longevity.
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 - 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:
IEC 61373 - V2G ready:
Fully bi-directional
Applications
The C330 is designed for stationary use in charging stations, energy storage systems or photovoltaic applications.
