The ruggedly constructed feed-thru capacitors are highly reliable units for general use in screen rooms and other environments. It has four threaded inserts for easy installation on metal enclosure. Its M6 threaded feed-thru stud will allow power current of 100 Amps without heating or voltage loss. These have low dissipation factors, high temperature ratings, high insulation resistance, doubly rated dielectric strength, and long life. A bleeder resistor is included within the capacitors, to discharge the capacitors when applied voltage is removed.
