What is the average life of your circuit breakers?
Answer
The life of a circuit breaker is determined by a number of factors.
For example:
The number of normal switches ON/OFF
Whether an electrical load current is present at the time of tripping
Tripping on a short circuit and the level or intensity of that short circuit
Lastly, the actual site conditions can also have a major effect on service life. Excessive contaminating dusts / fumes moisture etc
Remember, just because the circuit breaker is ON and the power is being supplied is no guarantee it will stay like that and even more importantly whether it will effectively trip when required to do.
Always make sure you purchase the best quality you can afford from a supplier you can trust.
They are certainly not expensive if one gets good life from them and you can have confidence they will trip when needed!
