Ballast lamps equate to fluorescent, mercury vapor, sodium vapor and quartz loads and will operate at a maximum of 600V. Filament lamps equate to incandescent, infrared, sodium iodine and heating loads and will operate at a maximum of 480V. Resistance heating equates to radiant and convection heating, furnace and oven loads. Type CN35 electrically held lighting contactors are designed to handle the switching of tungsten (incandescent) or ballast (fluorescent and mercury arc) lamp loads as well as other non-motor (resistive) loads. Ideal applications include industrial plants, stadiums, parks and any new construction requiring lighting control.
