DC contactor is mainly used to control DC circuit, such as main circuit, control circuit and excitation circuit, etc. 400A DC contact relay is available with energy-saving board, optional auxiliary contact 1NO, 9V-36V coil rated voltage, is a high voltage DC contactor with max. switching voltage 1000V DC, widely used in hybrid electric vehicles, charging piles and other fields.

Features and Benefits

  • 400A contact switching capability, max. switching voltage 1000V DC.
  • The high voltage DC contactor has a set of normally open bridge contacts (screw type) and the contact loop is non-polar.
  • Ceramic brazing technology is adopted, contacts will not be oxidized and can be quickly cut off at DC high voltage.
  • Compact size and light weight, sealed structure for main contact, suitable well for working continuously in harsh environment.
  • Flexible installation and 12V/ 24V DC various coil voltages are available to meet the various needs.
  • Low coil power and energy-saving type DC contactor.
  • Optional coil lead length 150mm or 390mm or other customized length.
  • Application: Telecom equipment, solar system, engineering machinery, electro mobile, electric vehicle, charging system, train, ships, UPS, etc.
