HONGFA HFE82V-150F is a hermetically sealed high-voltage DC contactor rated for 150A continuous current at 750V DC with 150kW maximum switching power and 1300A (400V DC) overcurrent breaking. The single-pole 1 Form A (SPST-NO) contact, ceramic brazing seal and hydrogen-filled arc chamber meet IP67 protection and IEC 60664-1 insulation requirements, and there is no polarity requirement on the load or coil side. This Q5Y type brings the coil out to QC (quick-connect) terminals for fast harness assembly, while load connections use female-thread M5-class studs. The HFE82V-150F is listed in HONGFA’s vehicle-series application table for EV/PHEV main, precharge and fast-charge relays and is equally at home in industrial DC switching duties.
Carries 150A continuously at 85°C and breaks up to 1300A at 400V DC (1 operation) for overcurrent faults, with an 8kA/2ms short-circuit withstand — no fire, no explosion.
Rated for 750V DC load systems with 150kW maximum switching power — the 750V type of the HFE82V-150F series (500V and 750V types available).
The Q5Y variant terminates the 6W single coil with QC (quick-connect) tabs for simple, tool-friendly harness assembly; a connector (C5Y) variant is available per the ordering code.
No polarity requirement on either the load or coil side simplifies wiring and reduces assembly errors — a practical benefit of the HFE82V ceramic-sealed platform.
Ceramic brazing prevents arc leakage; hydrogen filling protects contacts from oxidation and burnout, keeping contact resistance low (≤0.5mΩ at 150A) and stable.

It carries 150A continuously at 85°C ambient. Graded overload capability: 180A for 2h, 225A for 15min, 320A for 2min, 400A for 1min, 600A for 20s and 900A for 8s (wire cross-section ≥50mm²).
No. Official HONGFA data defines HFE82V-150F as a single-pole 1 Form A (SPST-NO) DC relay. Marketplace "phase / 50Hz" wording is AC-contactor template residue and does not apply to this DC product.
The F series covers 500V and 750V DC load types (ordering code positions for 500 / 750 VDC). This listing is the 750V type rated at 150kW maximum switching power. Confirm the load-voltage type when ordering.
12V and 24V DC coils are standard, both 6W with pick-up at ≤75% of rated voltage. The Q5Y type uses QC (quick-connect) coil terminals; a connector-coil C5Y housing variant is also produced.
Mechanical endurance is 2×105 operations. Electrical endurance includes 5×104 breaking ops at 475V DC / 20A, 7×104 making ops at 20V DC / 100A, 1×103 breaking ops at 450V DC / 150A and 500 ops at 750V DC / 150A.
Both are 150A-class HFE82V members. HFE82V-150F (this page) is the F series with 1300A breaking at 400V DC, 150kW, 6W QC quick-connect coil and a 77.0 × 37.7 × 71.3 mm body; HFE82V-150D has 1200A breaking at 300V DC, 225kW (750V type), a 5.5W wire-lead coil and a 76.0 × 36.0 mm body.
