  • Epoxy sealed. Epoxy resin encapsulated seal structure allows the working in explosive and harmful environment and coils and contacts will not be oxidized and polluted.
  • High efficiency coil. The energy-saving coil holds 1.7~2.0W power, counter electromotive force up to 0V.
  • Non-polarity. There is no polarity requirement for contacts and coil connections.
  • No electromagnetic counter force.
  • Compact design, low noise.
  • Meet CCC, RoHS, CE and ISO9001 conformance requirements.

Applications: High voltage DC contactor has 1NO contact, which is used in electric control systems such as automotive electric winches, telecommunication equipment, construction machinery, battery trucks, electric forklifts, trains, ships, uninterrupted power supplies, etc.
