250A High Voltage DC Contactor Features:

  • DC 12-750V rated load voltage of contact circuit.
  • SPST-NO of contact form, 12 volt, 24 volt coil for selecting.
  • Main contact voltage drop at 250A, not above 100mV.
  • The connection of contact and coil need to be nonpolarity.
  • Efficient coil, retentive power is only 2-2.3W, counter electromotive force is 0V.
  • The joint way of the coil is very convenient.
  • The coil has no counter force of electromagnetism.
  • Compare to the similar products, this product is smallest and lightest.
