  • 12 Volt DC contactor and 24 Volt DC contactor coil are optional.
  • 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, Low energy consumption, low heat.
  • Meet CCC, RoHS, CE and ISO9001 conformance requirements.

Applications: High voltage DC contactor has normally open type (SPST-NO, 1NO) contact form, 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.
