The C310 series are 1-pole AC and bi-directional DC NO contactors up to 1,500 volts rated insulation voltage, with conventional thermal currents up to 500 amps.
The bi-directional DC contactors switch high power in a small space. They ensure safe disconnection of high loads regardless of the direction of the current and provide reliable protection in the event of a system fault. Full bi-directionality is essential in battery storage systems and electric vehicles.
Typical applications include use as the main contactor in battery management systems for HV vehicle batteries, in charging stations for modern electromobility, in battery test benches or in combiner boxes for photovoltaic systems and inverters of all kinds.
