DC contactor C300

high-powerelectromechanicalsingle-pole

The bi-directional DC contactors switch high powers in a small space. With a making capacity of up to 2,500 amps, the compact switchgear is suitable for applications with high inrush current or high capacities. All versions can carry up to 500 amps continuously. In the event of a short circuit, 5,000 amps, can even flow for 20 milliseconds without the contacts welding. The contactor therefore maintains its full function in order to disconnect high power ranges if necessary up to 500 amps and up to 1,500 volts – irrespective of the current direction. This full bi-directionality is important for systems with a charging and discharging process, such as in battery networks or electric vehicles. Typical applications are the DC circuit in inverters, e.g. in photovoltaic applications, battery storage and chargers. • Super-compact dimensions – high rated insulation voltage Ui up to 1,500 volts • High conventional thermal current Ith up to 500 amps • Making capacity Icm up to 2,500 amps • Short-time current-carrying capacity Icw up to 5,000 amps • Full bidirectionality – reliable disconnection of high performances • Auxiliary switch with mirror contact function Applications • E-mobility • Stationary energy storages
