Depends on the use, and the reason for it tripping. If an electric breaker is used as a “Switch” then the thermal, bi-metal types will fail earlier from wear on the contacts. But for a 'regular' household residential use, only when it fails, which should be in 50 to 100 years after installation.

Check each appliance for overheating when you unplug it.How many times can a circuit breaker be reset?
Now, if you happened to plug in several appliances to that circuit AND you know the draw of the total of those appliances is greater then 15 Amps, then, and only then should you reduce the load on that circuit (unplug things), reset the breaker – only once.Can I replace a 15 amp breaker with a 20 amp breaker?

The most common cause of circuit breaker failure is overloading it, causing it to trip out or open the circuit. Repeated tripping of the circuit breaker will cause it to become unstable and therefore trip out before it reaches it's maximum amperage, or maybe not trip at all.How do you fix a circuit breaker?
