Overview
The Intermatic LC4536LA is a locking-type thermal photocontrol engineered for reliable automatic lighting control in street lighting and commercial outdoor applications. The LC4500 Series Photocontrols feature low cost locking-type mounting, and thermal-type controls for street lighting and other applications requiring a twist and lock type plug connection. Thermal-type photocontrols provide dusk-to-dawn lighting control and a delay action, which eliminates loads switching OFF due to car headlights and lightning. This model is ideal for facility managers and electricians who need a tamper-proof, quick-installation solution for outdoor lighting.
