(Contact circuit rated load current 400A)

Used in electric vehicles, hybrid electric vehicles, construction machinery, photovoltaic, DC voltage power supply control system.

  • Nonpolarity—The connection of contact and coil need to be nonpolarity.
  • Epoxy Sealant—Sealed by epoxy resin. It can work in the hostile environment, Coil and contact cannot be oxidized and polluted.
  • Efficient Coil – Optional built-in energy-saving coil,retentive power is only 2-2.3W, counter electromotive force is 0V.
  • ROHS authentication is totally meet the requirement of ROHS, It is benefit to body health and the environment protection.
  • Compare to the similar products, this product is smallest and ligtest.
  • The coil has no counter-force of electromagnetism.


The product have one normally open contact, for electric vehicles, telecommunication equipemnt, engineering machinery,car batteries,electric forklift trucks,trains,ships,electronic control systems such as uninterruptible power supply.
