Intermatic T174 24-Hour Mechanical Time Switch with Skip-a-Day, 208-277 VAC, 60Hz, DPST, Indoor Metal Enclosure, 1 Hour Interval

Similar to the T100 Series, these time switches can also handle electrical loads up to 40 A per pole. The T170 Series Time Switches allow for up to 10 ON/OFF settings per day, but give you the additional capability of skipping days in which the loads may not be needed. Each time switch will come with one set of ON/OFF trippers as well as three skipper screws to omit the schedule for at least three days.

Features:

  • Controls loads up to 40 A per pole
  • Direct 24-hour control of most loads
  • Up to 10 ON/OFF operations each day
  • Minimum ON/OFF times of one hour
  • Manual override
  • One ON and one OFF tripper and three day-skipper screws included

Applications:

  • Indoor Lighting Control
  • Timing/Scheduling ON/OFF
