NSI W222L Series W Different Schedules Each Day 7 Day Time Switch with Reserve Power, Metal Indoor NEMA 1, 208-277 Input Supply, DPDT Output Contact

This NSi Industries W222-L mechanical time switch accepts 208-277 VAC input and can activate a 40 amp load or 5 hp motor. A spring-wound backup power supply preserves timer settings up to 24 hours. The timer includes one pair of contact trippers per day and is suitable for individualized daily operation. The timer has a minimum On cycle time of one hour and a minimum Off cycle time of two hours. A switch allows operation to be skipped for individual days of the week. The double-pole double-throw (DPDT) contacts are housed within a metal enclosure that meets NEMA-1 standards for dust resistance and has a lockable hasp. The enclosure is suitable for indoor use and mounts to an external surface. This mechanical timer is Underwriter Laboratories (UL) listed and Canadian Standards Association (CSA) certified for quality assurance and is suitable for controlling parking lot lighting, HVAC, display lighting, security lighting, lighted signage, and storefront lighting.SpecificationsSwitch typeMechanical 7-day timer, contact trippers for one on/off cycle (included).

Time activated switches (also known as timers) operate at preset time intervals during a daily or weekly period and can be either mechanical or electronic. Mechanical timers feature a dial with multiple pins to set the on/off time intervals. Electronic timers feature an LCD display and pushbuttons to set the time intervals. Light activated switches (also known as optical or photo) operate when ambient light levels reach preset values, generally measured in foot candles. Motion-activated switches (also known as motion sensors) operate when an electronic field of a preset range is interrupted. These switches can include energy saving logic that uses combinations of time, light, and motion to operate and can include one or more device outlets or circuit contacts. Automatic switches are used to control indoor lights, outdoor lights, appliances, and small equipment motors.NSi Industries manufactures electrical components and sensors, lighting products, and energy management products. The company, founded in 1975, is headquartered in Huntersville, NC.
