Tripping the breaker right away on mains power almost always means the AC heater is shorted to ground. Check it with a meter from each lead to the metal housing. Our heaters are the 120V US versions, though, so for a 230V Thetford N3150 you'll need to get the correct heater from a Thetford dealer where you are.
