WebLine choke is an inductance connected to the VFD input or output circuit. It is a component that forms a magnetic field as current flows through it and when the current increases, it limits the increment in current by producing a voltage or emf across it that opposes it. This protects the VFD from unwanted spikes, transients, and harmonics.
