RC filter – Three Phase

Spark Quenchers are used in electrical applications to suppress back EMF generated in inductive load and also used in protection of Solid State switches. They are installed across the load or across the output contacts switching the load. This reduces occurrence of arcing and noise generation in relay and switch contacts.
