Verified against the official HONGFA HFE80V-200 datasheet (2021) and HONGFA-authorized distributor parameter data. Single-pole 1 Form A; "2-Phase" in the listing title is marketplace template residue.
HONGFA HFE80V-200 is the 200A-class main DC relay of the HFE80V family, positioned by HONGFA as the preferred relay for micro / low-speed electric vehicles (LSEV). It carries 200A continuously at 85°C in an 88.0 × 47.7 × 88.0 mm vertical-mount body weighing about 370g, with female-thread screw load terminals for low-resistance power wiring. The AgSnO2 single-pole 1 Form A contact keeps contact resistance at ≤0.5mΩ (250A), and the contact switches a 150VDC / 200VDC-rated load circuit — 250VDC maximum — up to 400A resistive with 80kW maximum switching power. The 6W coil (12V / 24V DC) pulls in at ≤75% of rated voltage, and insulation coordination complies with IEC 60664-1. In a battery disconnect unit the HFE80V-200 closes the main battery circuit after the HFE80V-20D pre-charge relay has softly charged the DC link — the two HFE80V siblings cover the main-contactor and pre-charge roles of the same BDU architecture.
HONGFA positions the HFE80V-200 as a preferred product for micro / low-speed electric vehicles (LSEV) — the 200A main circuit relay that connects and disconnects the traction battery in daily service.
Carries 200A continuously at 85°C ambient — enough margin for LSEV traction peaks without oversizing to a heavier 300A-class contactor.
Rated load types of 150VDC and 200VDC cover 48–144V-class NEV platforms, with 250VDC maximum switching and 80kW maximum switching power for the 200A contact rating.
AgSnO2 contacts with ≤0.5mΩ resistance measured at 250A keep steady-state power loss low in the main battery path.
Female-thread bolt load terminals accept power lugs directly, and both horizontal and vertical mounting orientations are supported for flexible BDU / PDU packaging.
Manufactured by Xiamen Hongfa under ISO 9001 / IATF 16949 quality systems. RoHS compliant, meets IEC 60664-1 insulation coordination, and rated for 2×105 mechanical operations.

Main battery contactor duty in low-speed / micro electric vehicles — HONGFA’s official preferred application for the HFE80V-200 200A class.
Main-relay role in BDU / PDU modules, closing the battery circuit after the HFE80V-20D pre-charge relay charges the DC link.
DC battery and auxiliary load switching in bus and logistics-vehicle high-voltage systems within the 150/200VDC-rated envelope.
Contactors the charging and DC-link paths of 48–144V-class NEV systems where the 200A / 250VDC maximum rating fits the circuit.
No. Official HONGFA data defines HFE80V-200 as a single-pole 1 Form A (SPST-NO) DC relay. The "2-Phase / Phase: 2 / Number of Pole: 2" wording in the listing title, URL slug and item specifics is AC-contactor template residue and does not apply to this DC product.
250VDC is the maximum switching voltage, not a continuous rating. The official rated load voltages are 150VDC and 200VDC ordering types. Size the contactor for your nominal bus voltage (150V or 200V class), and keep peak switching at or below 250VDC per the datasheet.
The official value is ≤0.5mΩ measured at 250A. Some marketplace listings show "1mΩ" without a test condition — always compare resistance at the stated measurement current (250A) when checking incoming goods.
They fill two roles in the same HFE80V family. The HFE80V-20D is the 20A-class pre-charge relay that charges the DC-link capacitors; the HFE80V-200 (this product) is the 200A-class main relay that carries and switches the battery circuit. In a BDU they work as a pair — pre-charge first, then main close. Tell us your bus voltage and load current and we will confirm the correct HFE80V sibling for each position.
Mechanical endurance is 2×105 operations. Electrical endurance depends on the switched load: official data lists 1×104 operations at 150VDC / 40A and 3×103 operations at 150VDC / 200A (resistive). The HONGFA summary table also lists 500 operations for the full-rated condition — confirm the endurance grade for your exact voltage and current against the ordering datasheet before quoting cycle life.
Specify the rated load type (150VDC or 200VDC), coil voltage (12V or 24V DC) and mounting orientation (horizontal or vertical). The coil pulls in at ≤75% of rated voltage, so check your driver output against the 6W coil draw. Contact us with these details and we will confirm price, stock and lead time.
