Review: Funktioniert wie gefordert - Die Hupe eines Traktors sollte über ein Hitzerelais geschaltet werden. Der vorhandene Strom reichte für die Hupe nicht aus. Dank Relais funktioniert nun alles wie es soll.

## Questions & Answers

**Q: Will this send 12V power to the output only if the input voltage hits around 12V and not when it is at its usual 6V.**
A: I don't know what voltage/amperage it takes to trigger the relay.  The output voltage would match the input voltage, not increase or decrease it.

**Q: Is this a continuous duty relay ?**
A: As far as I know it is, I used it to replace my cars blower relay and when that's on it stays on until the end of the drive 20 min to 2 or 3 hours.  So I would say yes.

**Q: Does this relay make a sound when it closes/opens the circuit?**
A: Yes it does when you install it and turn on the item or you can test it with a 12 volt source,  if it doesn't make a clicking noise than it is no good and needs to be replaced.

**Q: What amperage rating is this relay?**
A: Hi,  I looked on the relay and did not see a amperage rating.  I used it for my tc40 tractor.  it was used for the glow plugs so it may be on the higher side.  good luck, don
