• Single-pole bi-directional DC contactors
• To 1500 volts
• Compact design
• Breaking capacity to 4500 Amps
• Ideal for high inrush currents or high capacitance
  

Compact single-pole NO contactors for AC and DC up to 1,500 volts rated insulation voltage. Making current up to 4,500 amps; conventional thermal current up to 500 amps; short-time current up to 6,000 amps. The bi-directional DC contactors C300 switch high power in the smallest space. With a making capacity of up to 4,500 amperes, the extremely compact series is suitable for applications with high inrush currents or high capacitances. All versions can carry up to 500 amperes continuously. In the event of a short circuit, even 6,000 amperes may flow for 20 milliseconds without the contacts welding. This means that the contactor retains its full function to separate large powers when required: up to 500 amperes and up to 1,500 volts – regardless of the direction of the current. This full bi-directionality is important for systems with a charging and discharging process, such asin battery storage or electric vehicles. Other typical applications are the DC circuit in inverters, combiner boxes in photovoltaic systems or the management of battery storage systems
