C303 – 1-pole bi-directional DC NO contactors up to 350 amps
C303–单极双向直流NO接触器,电流高达350安培
Compact 1-pole NO contactors for DC up to 1,500 volts rated insulation voltage, continuous currents up to 350 amps and high making and short-time currents. The C303 bi-directional DC contactors are compact, high-performance switchgear for applications with high making currents or large capacities. All versions can carry up to 350 amps continuously; in the event of a short circuit, significantly higher currents can flow without the contacts welding together. This means that the contactor retains its full function to disconnect high loads – up to 1.5 MW – regardless of the current direction. This full bidirectionality is important for systems with a charging and discharging process. Typical applications are DC circuits in inverters, in battery storage systems or in charging stations in the e-mobility sector.
