24-Hour SPST Timer Switch

The Intermatic T101PCD82 is a 24-hour electromechanical timer switch rated for 120V AC and 40A. It uses a single-pole single-throw contact rated at 2 hp at 120V and includes four trippers for scheduling up to twelve on/off cycles per day. A clear polycarbonate door protects the dial inside a NEMA 3R gray enclosure.

Suited for daily load control.

This timer suits installers who need a simple daily repeat cycle for pumps, lighting or HVAC loads up to 40A. It operates from -40°F to 130°F and mounts on a flat surface. Buyers who require multiple independent schedules, day-skipping features or astronomic timing should look at a different device.

Handles up to 23 hours on with twelve daily cycles

The dial allows a minimum on-time of one hour and a maximum of twenty-three hours per cycle, with twelve cycles available every twenty-four hours. Four trippers are supplied and extras are available under part number 156T1978A. The mechanism does not support shorter intervals, skip-day programming or battery-backed timekeeping during power loss.

Questions about this item

Will the 120 V AC supply and 40 A rating handle my existing pool pump motor?

The timer is rated for 120 V AC and 40 A with a 2 hp motor load at 120 V, so it will control a compatible single-phase pump within those limits.

Can I keep using my current 156T1978A trippers with this unit?

Yes, the switch includes four trippers and accepts extra trippers identified as 156T1978A, so your existing ones will fit.

How do I verify the timer is cycling correctly after I wire it?

Watch the dial advance through the 24-hour face; each on/off tripper should trigger the SPST contacts up to 12 times per day, confirming proper operation.
