CONCLUSION No evidence has been found to indicate that operational noise/humming is detrimental to the performance or service life of the circuit breaker. Visit our Community for first-hand insights from experts and peers on this topic and more. Issue:Is it common for a breaker to make a buzzing noise?
Windage noise is the cause of the majority of unexplained sounds that come from electric motors. It is more common in high-speed motors such as two and four-pole motors. The cause of this noise is obstructions located close to the rotating part of the motor.
In the few instances that this was not the case, the circuit breakers were evaluated and found to have acceptable performance and service life. CONCLUSION No evidence has been found to indicate that operational noise/humming is detrimental to the performance or service life of the circuit breaker.
Buzzing can be caused by micro-movements of ferrous materials inside the breaker due to the alternating magnetic field. Square D has investigated several instances of reported excessive noise/humming. In most of these instances, loose hardware, wiring, and current transformers have been found to be the cause.
For an experienced maintenance engineer, the normal sound levels of an electric motor can be known with regular inspections and checks, which will make it easy to notice any change in the motor’s normal observed sound. One of the best ways to check on a motor is to get to know its sound signature and to listen to it regularly.
when noticing an increase in motor sound, then you need to identify the reason for the excessive noises, here are some tips: Check motor alignment and mounting. Check the cover of the motor fan and the motor fan itself. Check the load of the motor. Check motor bearings; add some lubricants if applicable and check noise levels afterward.
