This Intermatic FF60MHC metal finish 875 watt maximum 60-minute auto-off spring wound in-wall timer features a rugged, brushed metal wallplate and is designed for abusive commercial environments. For maximum savings, the timer shuts off short-term use lights, fans, heaters, and other electrical components formerly controlled by single-pole wall switches after 60 minutes of use. This timer also includes a hold feature, allowing the user to temporarily stop the time cycle for continuous use of lights or electrical components. When the hold feature is disabled, the timer continues its cycle. With the included wallplate, this UL, CSA, and NEC listed timer is also designed for quick and easy installation with teeter type terminals and a 'press-on' knob design.
