Intermatic K4421M 120VAC 1800W Stem Photocontrol, Thermal Type

The K4400 series Photocontrols feature stem mounting, thermal-type, controls with single and multi-voltage models. Thermal-type photocontrols provide dusk-to-dawn lighting control and a delay action, which eliminates loads switching off due to car headlights, and lighting. 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 bimetal and composite resistor for reliable long life operation over ambient temperature extremes. These models are California title 24 compliant. "M" models are heavy duty die cast housings.
