Intermatic T103R – Frequently Asked Questions

1) Will the Intermatic T103R switch a 240V circuit, or is it 120V only?
The T103R is a 120 VAC, 60 Hz timer only. Its clock motor is wired for 120 volts, so it will not run on a 240V supply. The DPST switching does let it break both legs of a two-wire load on a 120V system, which is useful where the load has to be fully disconnected rather than just switched on one pole.
2) Can the T103R time switch be mounted outside on a building wall?
Yes. The T103R comes in a metal indoor/outdoor enclosure, so it can be surface mounted outdoors for parking lot, landscape, sign, and security lighting as well as indoors. The gray enclosure measures 10.125 in high, 6.5 in wide and 3.625 in deep, which is what you need to check against the wall space or panel area you are mounting it in.
3) How many on/off times per day can I program on the T103R, and how short can each period be?
Up to 12 ON/OFF operations in a 24-hour cycle, set by adding tripper pins to the dial. The shortest ON or OFF period is 1 hour, so it will not handle short-cycle scheduling like 15 or 30 minute runs. For lighting that goes on in the evening and off late, that is plenty; for anything needing sub-hour timing you need a different timer.
4) Will the T103R mechanism fit into an Intermatic enclosure I already have on the wall?
The T103R mechanism is built to fit most Intermatic enclosures, so if you already have a T100-series metal box mounted and conduit run to it, you can generally swap the works rather than redo the installation. The T103R itself ships complete with its own metal indoor/outdoor enclosure.
5) Does the T103R repeat the same schedule every day, or can I set different times for weekends?
It is a 24-hour timer, which means one schedule that repeats every day. There is no day-of-week skipping. If you need lights off on weekends or a different Saturday schedule, you want a 7-day timer instead of the T103R.
6) Can I turn the lights on manually without wrecking the T103R's program?
Yes, the T103R has a manual override lever so you can switch the load on or off immediately and the programmed trippers stay set. That is the feature property managers use most: a crew needs the lot lights on at 10 a.m. for work, then the timer resumes its normal evening schedule.
7) Is this a digital or mechanical timer, and does it lose its program in a power outage?
The T103R is a mechanical time switch from Intermatic's T100 Series, driven by a synchronous clock motor. The tripper pins are physical, so the schedule itself is never erased by an outage. What does happen is that the dial stops turning while power is off, so after a long outage the clock will be behind by the length of the outage and you rotate the dial back to the correct time of day.
8) What is the exact part number and who makes the Intermatic T103R?
Manufacturer part number T103R, made by Intermatic, part of the T100 Series of mechanical time switches, country of origin Mexico. Order by T103R to get the 120V DPST version in the metal indoor/outdoor enclosure; other T100 numbers cover different voltages and switch configurations.
9) Is the T103R suitable for controlling commercial parking lot and sign lighting?
Yes, those are listed applications along with landscape and security lighting, commercial building lighting, industrial facility lighting, and municipal and public lighting. It handles indoor and outdoor lighting control and general timed ON/OFF scheduling on a 120V circuit.
