40A 5-Pin Relay for 12-72V Systems

The Vszerda JD2912 is a 40-amp automotive relay designed for DC circuits from 12 to 72 volts. Its 1.8-watt coil and mounting hole suit vehicle control panels and accessory wiring. The five-pin layout supports changeover switching for lights, fans or pumps.

40A Switching Capacity and Voltage Range

It handles resistive loads up to 40 amps across 12, 24, 36, 48 and 72 volt supplies. The coil draws 1.8 watts, so it runs from standard vehicle electrics without extra drivers. Not for loads above 40 amps or AC mains voltages.

Highlights

  • Handles up to 40A switching for heavy automotive loads
  • Operates across 12V to 72V DC systems for wide compatibility
  • Low 1.8W coil power reduces electrical draw
  • Mounting hole allows secure installation in vehicle panels

Questions about this item

Will the JD2912 relay's 40 A rating work with my existing 12 V automotive wiring?

Yes, the relay supports 12 V, 24 V, 36 V, 48 V and 72 V coil voltages, so it will operate directly from a standard 12 V vehicle system while switching up to 40 A.

How can I verify the relay is operating correctly after installation?

Apply 12 V across the coil terminals and listen for a distinct click; then measure continuity across the switched contacts — they should show near-zero resistance when energised and open circuit when de-energised.
