INTERMATIC FF4H SPRING WOUND COUNTDOWN TIMER, COMMERCIAL, 125-277 VAC, 50/60 HZ, SPST, 4 HOUR MAX, WITHOUT HOLD, SILVER

The FF Series Commercial Countdown Timers are designed to replace any standard wall switch and do not require electricity to operate. These energy-efficient switches automatically limit the ON times for fans, lighting, motors, heaters, and other energy consuming loads. A commercial "brushed metal" look plate (plastic construction) meets NEC requirements. *NOTE: Not for use with sunlamps, saunas, or loads that could cause personal injury if timed incorrectly.
