Hongfa: The World’s Largest Relay Maker Behind Our HV DC Contactors

When a DC contactor sits between a battery pack and a 1500 V bus, “brand” stops being marketing and becomes a risk decision. Hongfa is the supplier we build that decision on.

Founded in Xiamen more than forty years ago and listed in Shanghai, Hongfa is now the largest relay manufacturer in the world by revenue and share — over 27% of the global relay market, held every year since 2017. It runs a “3+N” footprint across the Xiamen–Zhangzhou, eastern and western China bases plus Indonesia and Europe, with total assets above RMB 26 billion.

Scale matters less to us than what sits behind it. Hongfa makes its own precision parts, contacts and even the automation equipment that assembles the relays, so the chain is vertically integrated rather than bought in — which shows up as stable lead times, traceable quality on sealed HV DC devices, and room to scale when a programme doubles.

The families we stock

  • HFE82V (1000 VDC) — 100 A to 500 A continuous, ceramic-brazed hermetic chamber, IP67, 12 or 24 VDC coil.
  • HFE88P (1500 VDC) — 400 A, 600 A, 750 A for storage containers and fast-charging cabinets.
  • HFE85V — double-coil energy-saving versions, e.g. 300 A at 1000 VDC with auxiliary contact.
Hongfa HFE82V-200D 1000VDC 200A HV DC contactor
HFE82V-200D — 1000 VDC / 200 A, ceramic-brazed, IP67.
Hongfa HFE88P-600 1500VDC 600A HV DC contactor
HFE88P-600 — 1500 VDC / 600 A for storage and DC charging.

Capacity that is still growing

In September Hongfa ranked 65th on China’s Top 100 Electronic Information Competitiveness list, up eight places year on year. Weeks later the main structure of its Haicang Lingang Industrial Park was completed: RMB 998 million invested, 265,000 m², production from March 2027 and a planned annual output of RMB 2.5 billion — aimed at EV components, storage products, industrial relays and wind/solar electronics.

Qualifying a DC switching design for 2027? Send us voltage, continuous current and coil preference, and we will match the HFE82V or HFE88P part with a datasheet and a quote.
