High-voltage DC relay switches 150 A at 750 V with a 12 V coil

  • High-voltage switching up to 750 VDC
  • 150 A continuous current capacity
  • 12 VDC coil for low-voltage control
  • HFE82V-150D relay in new condition

High-voltage DC relay for 12 V systems

The HFE82V-150D is a 12 V coil relay rated for 150 A continuous current at 750 V DC. It suits engineers and integrators building high-voltage DC distribution, battery disconnect or EV charging circuits where a single-pole switch must carry heavy current reliably.

Thermals, noise and power draw

The coil consumes modest power at 12 V while the contacts handle 150 A with low resistive loss, so heat stays manageable in normal operation. The sealed relay runs silently, adding no audible noise to the enclosure.

Questions about this item

How is the HFE82V-150D relay installed and which wiring step is commonly missed?

Mount the relay securely, connect the high-voltage DC terminals to the 750 VDC circuit observing polarity, then wire the 12 VDC coil; the step often missed is adding a flyback diode across the coil to protect the drive circuit.

What maintenance or replacement will the HFE82V-150D relay need over time?

The relay is rated for 150 A at 750 VDC; plan to inspect contact resistance periodically and replace the unit when contact wear causes excessive voltage drop or the coil fails to actuate reliably at 12 VDC.
