High-Voltage Contactors

Gas-filled contactors for high-voltage safety disconnection up to 1500 V DC and 600 A DC

 Intro Pic

TDK’s High-Voltage Contactor (HVC) Series is designed to meet the demands of high-voltage and high-current DC applications, especially for disconnecting high-voltage lithium-ion batteries. The hermetically sealed and gas-filled ceramic arc chamber is based on more than 80 years of experience with gas tube technology. The HVC series can be used in a wide range of applications where fast and reliable disconnection of high DC voltages is required.

Operating ranges at a glance

Current (A DC)
Voltage (V DC)



The basic design consists of a moveable armature inside a hermetically sealed, gas-filled chamber. The armature is moved by an electromagnet and opens the contact to interrupt the high current. During disconnection of a high DC voltage normally an arc is generated.


Highly accurate and fast switching

The hermetically sealed ceramic arc chamber is gas-filled for highly accurate fast switching and ensuring reliable operation over the whole lifetime.

 Feature 1 switching-good

The TDK High-Voltage-Contactor Series extinguishes in 1.2 ms with clear break of current.

 Feature 1 switching-bad

The typical contactor part will extinguish in 4.6 ms with lots of fluctuations, which heats up the main contacts.

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

Contactless stuck detection – Hall


  • Available as Normally Closed (HC) or Normally Open (HO)
  • Tack welding proof – no tack welding of aux. contact possible
  • More than 1 million switching cycles
  • Short circuit proof due to ProFET technology inside
  • The Hall switch reacts only to the south pole of the indicator magnet only and is resistant to lateral stray fields.

The Hall sensor indicates a “Make” or “Break” depending on the presence of the magnetic field from the indicator magnet. It acts as a switch depending on the presence of a certain magnetic field. 
The indicator magnet is mounted to the axis, which is connected with the contact bridge. The up or down state of the axis changes the magnetic field sensed by the Hall sensor.

Single coil VS. dual coil

Single Coil

  • No additional current durig make (pick-up)
  • Operating power: 6 W, 0.5 A @ 12 V
  • No economizer required
  • Integrated coil termination
Neuer Inhalt

Dual Coil

  • Power during make (pick-up) 38 W, 3.2 A @ 12 V during 80...120 ms
  • Operating power: 4.2 W (0.35 A) @ 12 V
  • Hot-restartability (<1 s)
  • Works like an economizer but without the disadvantages of a PWM circuit
  • Integrated coil termination

Dual coil

Neuer Inhalt

  • High-voltage contactors are not designed to permanently switch under load
  • The device switches under load only in case of an emergency
  • Switching capability depends on voltage, current, inductance and resistance during break
  • Dual coil for increased lifetime of >50%: 3000 cycles with 300 A @ 450 V, 1000 cycles with 300 A @ 750 V

Bipolar contacts

The HVC has a bipolar design so that connection is possible regardless of polarity. This is a great advantage during assembly and also allows charging and discharging of a battery without using a second contactor.
