Intermatic® K4535 K4500 Thermal Photocontrol, 480 VAC, 7200 W Tungsten, 4000 VA Ballast, Twist Lock Mounting, Polycarbonate

The K4500 series photocontrols feature locking-type mounting and thermal type controls that are equipped with standard 3-prong locking-type plug connections. Thermal type photocontrols provide dusk-to-dawn lighting control and provide delay action, which eliminates loads switching OFF due to car headlights and lightning. The thermal type controls feature a cadmium sulfide photocell and sonic welded polycarbonate case and lens to seal out moisture. The design utilizes a dual temperature compensating bimetal and composite resistor for reliable long life operation over ambient temperature extremes.
