Features
- 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. Low energy consumption, low heat.
- Compact design, low noise.
- Meet CCC, RoHS, CE and ISO9001 conformance requirements.
Applications: 1000V dc contactor is 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.
