INTERMATIC K4136M PC STEM MNT 1800W 120V277V 1/2IN HUB DC

Photo control features stem mounting, thermal-type, controls with single and multi-voltage models. Thermal-type photo controls provides 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 sulphide 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.
