HVC43-MC Series and HVC45 Series High-Voltage Contactors

TDK HVC43MC series with integrated mirror contacts and HVC45 series with enhanced short-circuit current handling capability offer reliable switching of lithium-ion batteries for up to 1,000 V_DC in traction applications, energy storage systems (ESS), and DC charging stations. These components underscore TDK dedication to enabling the transition to a greener, more electrified future.

With an integrated mirror contact, according to IEC 60947-4-1, the HVC43MC enables safe detection of the main contact's position. This mechanically linked auxiliary contact provides reliable feedback about whether the main contact has opened or closed, enhancing system safety monitoring. The contactor can handle continuous currents up to 250 A and cut-off currents up to 450 A at 1,000 V_DC and 2,000 A at 450 V_DC, respectively, all in a compact package measuring 74.5 mm x 78 mm x 40.5 mm.

With a short-circuit current-handling capability of up to 12 kA for 5 ms, the HVC45 sets an industry benchmark, surpassing conventional solutions in its size class that typically achieve 8 kA to 10 kA. This enhanced capability addresses the requirements of modern high-energy-density batteries that can achieve higher short-circuit currents. The contactor can handle continuous currents up to 300 A and features a maximum cut-off rating of 900 A at 1,000 V_DC and 2,200 A at 450 V_DC, respectively.

Both series incorporate TDK proven gas-filled ceramic arc chamber technology and bidirectional switching capability, allowing current flow in both directions. The contactors are available with 12 V or 24 V coil voltages and are certified to CE, UKCA, and UL standards, supporting worldwide deployment.
