▍Features
1. The product complies with the EU RoHS directive.
2. Hermetically sealed and intrinsically safe. Not mounting position sensitive.
3. Operates in harsh environments without oxidation or contamination of contacts.
4. High voltage isolation between open contacts, inert gas filled contact chamber.
5. Product design and quality control in accordance to lATF-16949.
The 400A DC contactor, tailored for electric vehicles and energy systems necessitating moderate power management and swift switching capabilities, boasts exceptional current regulation and robust longevity, rendering it perfectly suited for powering circuits in electric vehicles, particularly those in light commercial vehicles and mid-sized energy storage solutions. Its compact design facilitates seamless incorporation into space-limited configurations while preserving reliability across diverse operational scenarios. This contactor guarantees efficient power management, minimizing energy wastage and prolonging the lifespan of associated equipment.
▍Coil Data
| Coil Voltage | Pickup Voltage | Dropout Voltage | Inrush Current | AVG.Holding Current | Holding Power |
