High-power contactor C320 series

electromechanicalDCAC

The Eddicy C320 series from Schaltbau stands for compact, single-pole & bidirectional DC and AC NO contactors from 1,000 to 1,500 volts. Short-circuit making capacity up to 3,000 amps. Continuous thermal current up to 1,200 amps. Short-time current up to 4,500 amps. The bidirectional DC contactors of the C320 series extend the application range of the successful C310 and C360 series. The compact devices switch even higher powers. With a rated short-circuit making capacity of up to 3,000 amps, the contactors are suitable for applications with high inrush currents. The devices can permanently conduct up to 1,200 amps – thanks to high contact forces with measurably less heating in the main contact system. In the event of a short circuit, as much as 4,500 amps may flow for 100 milliseconds without the contacts welding. This means that the contactor retains its full function in order to disconnect large powers when required, regardless of the direction of the current. This excellent breaking capacity is made possible by an efficient ceramic arc chamber with generously dimensioned air gaps. Features V2G-ready for bi-directional charging stations Compact dimensions — high rated insulation voltage Ui up to 1,800 volts High thermal continuous current Ith up to 1,200 amps High making capacity Icm up to 3,000 amps and an excellent breaking capacity Low energy consumption and low heating thanks to sophisticated coil saving circuit Safe disconnection of high powers Auxiliary switches with mirror contact function
