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.
