Bidirectional contactor C303

inverterpowermagnetic

The bi-directional DC and AC contactors of the C303 series are designed for operating voltages up to 1,500 volts and can carry currents of up to 500 amps continuously. Magnetic drives with three coil controls make the contactors versatile for use in modern industrial environments with ambient temperatures of up to 85 degrees. With a short-circuit switching capacity of up to 2,000 amps and a compact design, the C303 contactors are particularly suitable for applications that require high making currents or large capacities, but do not have space for large series. In the event of a short circuit, they can withstand 5,000 amps for 20 milliseconds without contact welding. This allows the contactor to retain its full functionality to disconnect high power independen­tly of the current direction when required. This full bi-directionality is important for systems with energy recovery, i.e., for systems with a charging and discharging process, such as charging stations and ESS applications. Other typical applications include DC circuits in inverters, combiner boxes in photovoltaic systems, battery management for emission-free drive systems, and stationary applications for grid stabilization.
