The C320 series are 1-pole AC and bi-directional DC NO contactors up to 1,800 volts rated insulation voltage, with conventional thermal currents up to 1,000 amps.
They ensure safe disconnection of high loads and provide reliable protection in the event of a system fault, with a very efficient ceramic arc chamber, double contact interruption and high breaking capacity.
Typical applications are use as the main contactor in battery management systems of high-voltage vehicle batteries, in charging stations for modern electric vehicles or in battery test benches.
