ProFusion Heater with solid state relay

I have a Pro Fusion 7500 watt electric garage heater (p/n EH-4604B). I want to wire in a SSR with a transformer to control the power to the heater with an external thermostat. Problem is the amp draw of the heater is 31.3 on 240 volts. Does anyone know the part number of a Solid State Relay with a built in transformer that can handle 31.3 amps? Or does anyone have a suggestion on how to do wire this heater so that I can use it with an external thermostat? I've included links to the wiring diagrams of the heater and to a SSR made by aube technologies that is an example of what I'm looking for. Thanks for any thoughts or ideas.

Welcome to the forums.

I'm not aware of a self contained unit that will switch that much current. Normally I'd use a contactor but that could be loud and annoying. You may want to consider using a stand alone solid state relay with a small power supply and a thermostat.

Here's an example of a SS relay. I wouldn't consider using anything under 40A. I'd use the 50A model.
