Device to prevent popping the circuit breaker if device draws too much power?
If you could even do this then you will burn down the building when the wire in the wall melts. You are pulling 27 A using 3kW on 110V using that machine alone.

Instead you should get a 240V line to your reflow machine. There is a reason high power devices are 240V, the required current is halved by doubling the voltage.

If you have a split-phase supply (where a neutral is shared between 2 opposing live phases) then you can pull the 240 V from that. However there are various regulatory restrictions on using a circuit like that. Talk to the owner of the place.
