Solenoid Coil Whine / Resonance (Undervoltage Release Coil of Circuit Breaker)
Solenoid Coil Whine / Resonance (Undervoltage Release Coil of Circuit Breaker)
(OP)
Does anyone know as to whether there is a means to reduce the resonance noise produce from a AC solenoid (in this particular case the solenoid is a undervoltage release coil installed in a circuit breaker). I have been told by the manufacture that the coil is 240Vac 50Hz rated and that the noise is normal which I question. I have measured the power supply voltage and it is 244Vac at 50Hz.
Please see link for video of the noise produced by the solenoid.
