Hongfa HFE82V-250C High-Voltage DC Contactor

The Hongfa HFE82V-250C High-Voltage DC Contactor is a robust, heavy-duty electrical switching device engineered for advanced energy and electric vehicle (EV) applications. Manufactured by Xiamen Hongfa Electric Power Controls Co., Ltd. (a leading global relay manufacturer), this high-performance contactor is specifically designed to safely "make and break" high-voltage DC circuits, handling up to 750V DC and 250 Amps of continuous current.

Key Specifications:

• Category: Automotive Parts & Accessories / EV High Voltage Components / DC Contactors & Relays

• Product Type: High-Voltage Main DC Contactor

• Manufacturer: Xiamen Hongfa Electric Power Controls Co., Ltd.

• Model / Part Number: HFE82V-250C (750-12-H-C5-1)

• Maximum Switching Voltage: 750V DC

• Rated Continuous Current: 250A

• Coil (Control) Voltage: 12V DC

• Control Connection: 2-Pin integrated side receptacle socket

• Housing Material: High-temperature, flame-retardant synthetic resin

Key Features:

• Safe High-Voltage Switching – Equipped with magnetic arc blowout technology that instantly stretches and extinguishes the dangerous electrical arc created when disconnecting a live high-current DC circuit.

• Hermetically Sealed Chamber – The internal electrical contacts are sealed (typically with inert gas or vacuum) to prevent oxidation, eliminate the risk of fire/explosion in volatile environments, and ensure long-term reliability.

• 12V Control Circuit – The 2-pin side connector operates on standard 12V automotive logic, allowing the vehicle's Battery Management System (BMS) or ECU to safely engage and disengage the massive high-voltage battery power.

• Compact Power Density – Features a highly space-efficient footprint with heavy-duty base mounting flanges, making it easy to package inside tight battery boxes or High Voltage Power Distribution Units (HV-PDU).

Ideal For:

• Main battery pack contactors (Main Positive / Main Negative) in factory Electric Vehicles (EVs)

• Custom EV conversions and high-performance electric drivetrains

• DC Fast Charging stations and EVSE infrastructure

• Solar array (PV) inverters and high-capacity Battery Energy Storage Systems (BESS)

• Heavy-duty industrial DC motor controllers
