High-power contactor C320 series

electromechanicalDCAC

Compact single-pole NO contactors for AC and DC (bidirectional) up to 1,800 V rated insulation voltage. Conventional thermal current up to 1,000 A; short-time current up to 5,000 A The C320 is a single-pole AC and bi-directional DC contactor in the power class up to 1,000 A. It ensures that high loads are switch-off safely and provides reliable protection in the event of a fault in the system. Typical applications are the use as main contactor in battery management systems of high-voltage vehicle batteries, in charging stations for e-mobility, in battery test benches but also in the DC circuits of inverters of photovoltaic systems. A very efficient ceramic arc chamber, double-break contacts and high breaking capacity are important features of the new contactor. Features - Compact dimensions – high rated insulation voltage Ui up to 1,800 volts - High making capacity Icm up to 4,000 amps and an excellent breaking capacity - High thermal continuous current Ith of up to 1,000 amps and high rated short-time withstand current Icw up to 5,000 amps - Full bidirectionality – safe disconnection of high power independent of the current flow direction - 4 auxiliary switches with mirror contact function for diagnosis and switching status monitoring - Low energy consumption and low heating thanks to sophisticated coil saving circuit Specifications (preliminary data) C320K, C320S Type of voltage - DC bidirectional, AC (f ≤ 60 Hz) Main contacts, configuration - 1 NO Rated operating voltage Ue - C320K: 1.500 V
