(Contact circuit rated load current 100A)

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 and one normally close contact, for electric vehicles, telecommunication equipment, engineering machinery, car batteries, electric forklift trucks, trains, ships, electronic control systems such as uninterruptible power supply.
