The fuse rating for a 22 kW motor depends on the starting current and the type of motor.
The starting current of the motor should be considered when selecting the fuse rating.
The type of motor (e.g. induction, synchronous) also affects the fuse rating.
Consult the motor manufacturer's specifications or a qualified electrician for the appropriate fuse rating.
A general rule of thumb is to use a fuse rating of 125% of the m

The unit of vibration is Hertz (Hz).
Vibration is a measure of the frequency of oscillation of a mechanical or electrical system.
Hertz is the unit of frequency, defined as one cycle per second.
Vibration can be measured using instruments such as accelerometers and vibrometers.
Vibration is an important consideration in the design and maintenance of electrical systems.
Examples of electrical systems that may experience vibr...
