Intermatic K4251 120-Volt Thermal Photocontrols with Stem and Swivel Mounting

The K4200 Series Photocontrols feature stem and swivel mounting, with thermal-type controls. Thermal-type photocontrols, which are available in single or multi-voltage models, provide dusk-to-dawn lighting control and a delay action, which eliminates loads switching OFF due to car headlights, and lightning. The thermal-type controls feature a cadmium sulfide photocell and a sonic-welded polycarbonate case and lens to seal out moisture. The design utilizes a dual temperature compensating bi-metal and composite resistor for reliable long life operation over ambient temperature extremes. Volts: 120.
