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.
