Intermatic T103 120 V Mechanical Timer
The Intermatic T103 is a 120-volt DPST mechanical time switch designed for indoor use. It features a NEMA 1 steel enclosure measuring 7.75 inches high and 3 inches deep. The unit provides 24-hour scheduling for industrial, commercial, and residential electrical circuits. It handles loads up to 40 amps with a 2 HP motor rating.
Suits fixed 125 V loads up to 40 A
This timer suits installations requiring a simple 24-hour repeat cycle on a 120-volt supply. It is not for circuits exceeding 40 amps or 125 volts. Buyers needing multi-day programming, astronomic functions, or outdoor-rated enclosures should look elsewhere.

Questions about this item
Does the mechanical 24 hour dial need periodic lubrication or replacement?
The T103 uses a self-contained synchronous motor and gear train that runs continuously; no user lubrication is required and the mechanism is not designed for field replacement.
What is the first limit reached when the switch runs a 40 A load continuously?
The 2 HP motor rating at 125 V will be exceeded before the 40 A contact rating, so motor-load heating becomes the limiting factor.
