Overview

The NSI Industries 5403A is a 3-pole 120V AC contactor with integrated TurnLock photocontrol for automated dusk-to-dawn lighting. Designed for heavy-duty outdoor applications, it delivers 40A resistive load capacity, 30A tungsten rating, and supports 3HP @ 120V or 7.5HP @ 240V motor loads. The photocontrol features instant ON and 3-5 second delay OFF to prevent false switching from passing vehicles or transient light. Housed in a NEMA Type 3R enclosure with grey enamel finish, it meets UL773 and ANSI C136.10 standards. Ideal for street lighting, parking lots, building perimeter illumination, and outdoor signage where reliable, weather-resistant switching is required. The 3PST switch type and 3-prong turn-lock receptacle ensure compatibility with standard photocontrols. With a power consumption of 3 watts during daylight, it provides energy-efficient operation. The conformal-coated cadmium sulphide photocell resists moisture and airborne contaminants, responding to light spectra similar to human vision. The heavy-duty die-cast zinc housing and gasketed design maximize weather protection.
