The 12V DC power from your dist. panel goes to that furnace CB/on-off switch then to motor.
They are a heat sensitive device to protect motor....circuit.
They are of a slow blow style.
Heat from furnace or short amperage spikes will not cause them to trip.
The motor will have to produce an excessive and prolonged amperage draw to trip it.
When it trips, a problem exists.
Voltage and amp readings should be taken after resetting.
You could have a power source, breaker or motor problem.
(Low voltage/higher amp draw------weak breaker/on-off switch or failing motor)
Take voltage/amp readings with blower running on both sides of switch.
