It is possible that whatever tripped the breaker damaged the new one. Have you tried disconnecting the pumps (again) and resetting the breaker?
So with all the pumps and the heater disconnected the breaker is resetting?
Just to clarify, with all the pumps and the heater disconnected from the circuit board the 50 amp breaker is still tripping? Can you locate and disconnect the ozonator and try the breaker again?
That is a very good idea. By disconnecting the main power wires and capping them you can narrow it down to the breaker itself or the wires between the breaker and the spa circuit.
