C330 – DC bi-directional switching

High-performance contactors for high-end applications with switchting voltages up to 1,500 volts and continuous currents up to 3,000 amps. Thanks to permanently extremely low contact resistances, contact heating is significantly reduced, which minimizes energy losses and significantly increases the efficiency of the overall system. The lower heat input reduces cooling requirements, lowers system costs, and increases the service life of the components—ideal for reliable use in modern high-performance fast charging stations for MSC Level 2 and Level 3.

The compact air contactor with permanent-magnet arc extinguishing and without gas encapsulation equalizes excess pressure. This ensures long, trouble-free operation in demanding environments without explosion hazards.

All versions of the C330 can reliably switch high currents and voltages when required, regardless of the direction of current flow. These properties are achieved through the special arrangement of blow magnets and arcing chambers.

Bi-directional contactors are required for the perfect interaction between electric vehicles and charging stations. These enable electric vehicles not only to charge, but also to feed electricity into the grid or use it for the domestic power supply.

The compact design has been specially developed for use in industrial applications and allows for easy integration even in limited installation spaces. This allows existing system layouts to be used flexibly, reduces installation costs, and enables new and existing applications to be implemented efficiently.

The C330 contactors have an integrated auxiliary contact with mirror contact function according to IEC 60947-4-1, annex F. Mirror contacts are required in feedback circuits of safety controls. The mirror contact function informs about the switching state and ensures that the NC contact of the auxiliary contact is not closed at the same time as the NO main contact.
