Time Switch

[Den]

I need a time delay switch to turn off after 1 hour
this is to connect two terminals on a heat pump 47v low power I need a switch that can disconect these wires after the one hour period
I was thinking a 230v switch and relay to disconect the low voltage terminals where can I get one
Are these even avilable

Thanks Den
