If the label said Ozone then it is the ozone unit not the heater, it is probable that the ozone unit is causing the breaker trip. I would disconnect the ozone from the control box and then try and reset breaker if it stays on then the ozone unit is bad and you can either replace it or do without, the ozone is not essential for the spa to operate.
