Unique-Bargains JD2912 40A 72V SPDT relay 5pcs

SKU CH-RRKT-4VD12 MPN JD2912

Pack of five 40A SPDT relays with 72V DC coils for automotive electrical circuits

  • SPDT contact type switches two circuits from one coil
  • 40A rating handles high-current automotive loads
  • 72V DC coil voltage suits heavy-duty vehicle systems
  • Five pins simplify wiring into standard relay sockets
  • Pack of five relays covers multiple circuit installations

Product Identity

The Unique-Bargains JD2912 is a pack of five SPDT automotive relays rated at 40A with a 72VDC coil. They are designed for mechanics and DIYers who need reliable switching for vehicle electrical circuits such as lighting, fans, wipers and climate control systems.

Suitability

This set suits anyone replacing or adding 5-pin 1NO 1NC relays in 72V DC automotive applications where a 40A contact rating is required. Buyers who need a different coil voltage, a higher current rating, a different pin layout or a normally-open-only contact arrangement should look at alternative parts.

Critical Specification

The defining specification is the 72VDC coil voltage combined with a 40A SPDT contact rating in a standard 5-pin footprint. Only circuits designed for this exact coil voltage and current capacity will operate correctly with these relays.

Highlights

  • SPDT contact type switches two circuits from one coil
  • 40A rating handles high-current automotive loads
  • 72V DC coil voltage suits heavy-duty vehicle systems
  • Five pins simplify wiring into standard relay sockets
  • Pack of five relays covers multiple circuit installations

Questions about this item

What coil voltage must the vehicle electrical system supply for the JD2912 relay to operate?

The JD2912 requires a 72VDC coil voltage to activate the switching contacts.

Will the 40A contact rating handle the same load as the original relay I am replacing?

The relay is rated for 40A at the contacts, so it can replace any unit with an equal or lower current rating.

How can I confirm the relay is switching correctly after installation?

Listen for an audible click when the coil is energised and verify the circuit powers on and off as expected.
