HONGFA HFE82V-1000 is the 1000A-class flagship of the HFE82V ceramic-sealed high-voltage DC contactor platform. It carries 1000A continuously at 85°C, switches up to 1200V DC at 1500kW and breaks 2000A (1200V DC, 1 operation) for overcurrent faults. The heavy-duty design terminates the load on M10 female-thread studs with copper bus-bar terminals and drives the single-pole 1 Form A contact with a built-in energy-saving double coil (50W drive for 0.2s, then 10W holding). Ceramic brazing sealing with hydrogen filling meets IP67 and IEC 60664-1, with no polarity requirement on the load terminals. The HFE82V-1000 targets high-power EV and stationary applications where 1000A-class sealed DC switching is required.
Carries 1000A continuously at 85°C and switches 1200V DC at up to 1500kW — the highest-power member of the HFE82V family.
Breaks 2000A at 1200V DC (1 operation) for fault clearing, with a short-circuit carrying capability of 10000A/8ms and 12000A/4ms — contacts may weld but the relay will not burn or explode.
A built-in PCBA drives the coil at 50W for 0.2s to close, then automatically holds it at only 10W — cutting continuous coil loss by 80% and minimizing heat in sealed enclosures.
M10 female-thread studs with copper bus-bar terminals handle 1000A-class bus work, and the load is polarity independent for simplified wiring.
Ceramic brazing prevents arc leakage; hydrogen filling protects the contacts from oxidation, keeping contact resistance low (≤0.1mΩ at 1000A) and stable over life.

It carries 1000A continuously at 85°C ambient (wire cross-section ≥400mm²). Graded overload capability: 1500A for 140s, 2000A for 82s, 3000A for 30s and 4000A for 18s, plus 10000A/8ms and 12000A/4ms short-circuit carrying (contacts may weld, no fire / no explosion).
No. Official HONGFA data defines HFE82V-1000 as a single-pole 1 Form A (SPST-NO) DC relay. Marketplace "phase: 2" wording is AC-contactor template residue and does not apply to this DC product.
The built-in energy-saving PCBA must be driven with a fast rising edge (step power supply). Do not drive it with a slowly rising voltage or it will not operate, and avoid repeated on/off commands within 0.2s of closing — the coil draws 50W only during the 0.2s drive phase, then drops to 10W holding.
Both load types exist in the HFE82V-1000 ordering code: 1000V DC and 1200V DC. The series maximum switching voltage is 1200V DC (2000A breaking rated at 1200V DC). Please confirm the load-voltage type (1000 / 1200V DC) and coil voltage (12 / 24V) when ordering.
Mechanical endurance is 2×105 operations. Electrical endurance: 3×104 making ops at 1200V DC / 60A, 1 breaking op at 1200V DC / 2000A, 50 breaking ops at 1200V DC / 1000A, 50 breaking ops at 1500V DC / 800A, and 1×104 switching ops at 1200V DC / 60A.
HFE82V-1000 is the 1000A-class flagship: 1200V DC / 1500kW / 2000A breaking, M10 screw-and-bus-bar load terminals, built-in energy-saving double coil and an approx. 3.5kg body measuring 165.9 × 104.6 × 132.8mm. Smaller family members (HFE82V-150D / 150F / 200B / 200W) are 150-200A-class parts in much lighter housings. All share the same ceramic-sealed, polarity-free platform.
