An auto reset circuit breaker is fine for a circuit that is not continuously energized. The hydraulic pump, for example, is only energized while you hold the switch to actuate it. If the circuit is overloaded the breaker will trip, cool, reset, trip, cool, reset ..... until you release the switch to de-energize the circuit.

But if the circuit was something that may be continuously energized such as a residential fridge, and the circuit was in overload, the breaker would trip/reset/trip/reset continuously until either the breaker completely failed, or the circuit overheated to the point of causing a fire or burned open. In that case, a manual reset breaker would be the better choice.

A manual reset breaker for the pump would be OK also, but would mean having to go open the front compartment to reset the breaker any time it tripped.
