Product Overview
The necessary change to environmentally friendly use of energy leads to the high demand for high-voltage and high-current DC applications.
TDK offers the High-Voltage Contactors (HVC) series which meet the requirements for High-Voltage DC emergency disconnection applications up to 600 A in electric cars, trucks, busses and DC fast chargers.
HVC series features excellent extinguishing characteristics in combination with a bipolar design for charging and discharging.


The main applications for HVC are charging stations as well as battery junction boxes of EV cars.
Always a pair of HVC is used on both sides entrance and outlet.
Examples of applications:

  • DC charger
  • Electrical energy storage
  • Commercial electrical vehicles
  • Battery junction boxes for electrical vehicles
Figure 1 : Applications


  • Hermetically sealed ceramic arc chamber, gas-filled for highly accurate, fast switching ensuring reliable operation over the whole lifetime.
  • Very high number of switching cycles
  • Up to 1500 V DC and 600 A
    The TDK HVC series provides a longer lifetime and increased reliability compared with existing products due to:
  • Less heat on the contacts
  • Less likely to become stuck
  • Less EMI
