Features
- Optional coil voltage: 12V DC contactor and 24V DC contactor.
- 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 2~2.3W power, counter electromotive force up to 0V. The standard type DC contactor and energy saving type DC contactor are optional.
- Non-polarity. There is no polarity requirement for contacts and coil connections.
- No electromagnetic counter force. The joint way of the coil is convenient.
- Compact design, low noise.
- Meet CCC, RoHS, CE and ISO9001 conformance requirements.
Applications: High-voltage DC contactors are used in electric control systems such as automotive electric winches, telecommunication equipment, construction machinery, battery trucks, electric forklifts, trains, ships, uninterrupted power supplies, etc.

DC Contactor Dimensions (unit: mm)
Notes: Sizes of some products are noted without dimensional tolerance. So, consider the tolerance of ±0.3 mm for dimensions less than 10mm, ±0.5 mm for dimensions 10-50mm and ±0.8 mm for dimensions more than 50 mm.
- Resistive load includes the maximum inductance up to 300 uH.
- It is recommended to do test for different situations according to the extrapolation.
- Dielectric strength drops to lower than 100mΩ at 1000VDC after life time.
- The maximum attracting current is 650A.
