Snubber Circuit For Contactor Coil. A flyback diode is sometimes called flywheel diode freewheeling diode relay diode or snubber diode as a flyback diode circuit is a type of snubber circuit. Why put a diode across a relay coil.
Connect snubber leads to each coil terminal of the contactor or solenoid. Snubbers are frequently used in electrical systems with an inductive load where the sudden interruption of current flow leads to a sharp rise in voltage across the current switching device inductive kick in accordance with faraday s law this transient can be a source of electromagnetic interference emi in other circuits. Additionally if the voltage generated.
If the snubber is connected in parallel to the switch the current flows through the protection circuit at switch off and then decays.
In your specific application we would use a s07k35 mov across each contactor coil. All contactor coils 3 phase motors and pumps that are operated by a contactor i e. In your specific application we would use a s07k35 mov across each contactor coil. Carousel swing arm motors.
