Verified against official HONGFA HFE82V-200W product data and datasheet excerpts (wire-lead coil type; outline 55.0 × 43.0 × 65.8 mm).
HONGFA HFE82V-200W is a compact, hermetically sealed high-voltage DC contactor rated for 200A continuous current at 750V DC load voltage with 180kW maximum switching power. 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. The W type uses wire-lead coil termination and a female-thread load terminal, and its compact 55.0 × 43.0 × 65.8 mm body suits space-constrained EV battery, ESS and DC-link designs.
Carries 200A continuously at 85°C ambient and handles abnormal conditions by breaking up to 7.5× rated overcurrent (1500A at 450V DC), giving robust protection in EV and ESS DC-link circuits.
Rated for 750V DC load systems with 180kW maximum switching power and 1500A breaking capability at 450V DC — a proven HFE82V platform for high-voltage EV and stationary battery applications.
The W housing is significantly shorter than the larger HFE82V-200B enclosure, saving space inside battery disconnect units and power distribution boxes where real estate is tight.
Coil termination is by wire leads for simple harness connection, and the load side uses a female-thread terminal for secure M6-class busbar mounting.
Ceramic brazing prevents arc leakage (no fire or explosion risk); hydrogen filling protects contacts from oxidation and burnout, keeping contact resistance low and stable.
Manufactured by Xiamen Hongfa under IATF 16949 / ISO 9001 / ISO 14001 / ISO 45001 quality systems. Factory test reports, RoHS compliance and certificate support are available for OEM qualification.
HONGFA HFE82V-200W series is designed and manufactured under international quality and environmental standards. Available certifications and reports include:
RoHS — Restricted hazardous substances compliance.
ISO 9001 / IATF 16949 — Quality management systems aligned with automotive component production (factory level).
ISO 14001 / ISO 45001 / IECQ QC 080000 / ISO 27001 — Factory environmental, occupational health, hazardous-process and information-security management.
IEC 60664-1 — Insulation coordination for equipment within low-voltage supply systems.
Factory Test Reports — Contact resistance, dielectric strength and switching-life test data available on request.
Main contactor, precharge and fast-charge relay duty in passenger EV and PHEV battery systems (family application table lists HFE82V-200W for these roles).
Compact main-relay switching in 48V mild-hybrid and low-speed EV battery circuits where wire-lead coil routing suits harness assembly.
Charge/discharge path and battery disconnect control in residential and commercial Li-ion storage cabinets and battery disconnect units.
DC-side switching in chargers, PV inverters and 750V-class DC distribution for commercial and industrial systems.
It carries 200A continuously at 85°C ambient. For abnormal conditions it can break up to 7.5× rated current (1500A at 450V DC, 1 operation), protecting the DC link from overcurrent faults.
No. Official HONGFA data defines HFE82V-200W 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 share the same 200A / 750V DC / 180kW electrical platform, but they are different housings: HFE82V-200W has a compact 55.0 × 43.0 × 65.8 mm body with wire-lead coil termination, while HFE82V-200B uses the larger 81.0 × 39.0 × 70.0 mm enclosure. Choose by mounting space and coil-connection preference.
Maximum breaking current is 1500A at 450V DC (1 operation), i.e. 7.5× the 200A rating. Switching/breaking endurance is 500 operations at 450V DC / 200A. Mechanical endurance is 2×105 operations.
12V and 24V DC coils are standard, both rated at 6W coil power with pick-up at ≤75% of rated voltage. The W type terminates the single coil in wire leads for direct harness connection.
