HONGFA HFE82V-200B is a hermetically sealed high-voltage DC contactor rated for 200A continuous current at 750V DC load voltage, with 180kW maximum switching power. Its 1 Form A (SPST-NO) contact, ceramic brazing seal and hydrogen-filled arc chamber meet IP67 protection and IEC 60664-1 insulation requirements. The load and coil sides have no polarity restriction, simplifying busbar and coil wiring in EV battery, energy storage and solar DC-link applications.
Carries 200A continuously at 85°C ambient (wire cross-section ≥60mm²) with overload steps up to 250A/15min, 320A/5min, 600A/30s and 900A/10s for demanding DC-link duty.
Rated for 750V DC load systems with up to 1000V DC max switching voltage and 180kW max switching power — a proven platform for high-voltage EV and stationary battery applications.
Ceramic brazing technology prevents arc leakage, eliminating fire or explosion risk; hydrogen filling protects the contacts from oxidation and burnout with low, stable contact resistance.
No polarity restriction on the load or coil side, giving design flexibility and preventing mis-wiring in bidirectional charge/discharge circuits.
Standard 12V and 24V DC coils with 6W coil power cover common vehicle BMS and control voltages; pickup ≤18V (24V coil) ensures reliable operation across the vehicle voltage range.

It carries 200A continuously at 85°C ambient (min. 60mm² wire cross-section). Overload capability is graded: 250A for 15 minutes, 320A for 5 minutes, 600A for 30 seconds and 900A for 10 seconds.
The official HONGFA datasheet defines HFE82V-200B as a single-pole 1 Form A (SPST-NO) contactor. The "2-phase" wording sometimes seen in marketplace listings is not an official designation. Both the load side and coil side are polarity-free.
Per the official 2024 datasheet: 1500A breaking at 450V DC (1 operation) and 1000A at 750V DC (1 operation), with 8000A (1ms) short-circuit withstand — no fire or explosion. Electrical endurance is 500 operations at 450V DC/±200A and 200 operations at 750V DC/±200A (0.6s on / 5.4s off).
12V and 24V DC coils are standard, both rated at 6W coil power. Pick-up voltage is ≤9V (12V coil) / ≤18V (24V coil); drop-out voltage ≥1V / ≥2V. Coil connections are polarity-free, but adding a flyback diode increases release time and can reduce life.
Contact resistance is ≤0.3mΩ measured at 200A (2024 datasheet value; some earlier listings quote 0.5mΩ). The contactor is hermetically sealed with ceramic brazing and hydrogen-filled, meeting IP67 with no risk of arc leakage.
