Intermatic T102 Timer

The Intermatic T102 is a heavy-duty 24-hour mechanical time switch engineered for high-amperage industrial and HVACR applications. As a SPST (Single Pole Single Throw) electromechanical control, this unit manages electrical loads up to 40 Amps resistive per pole, making it a reliable solution for 208-277V circuits. Designed for consistent cycling, the T102 allows for up to 12 ON/OFF operations daily with a minimum duration of one hour per setting, providing precise control over indoor lighting, heating systems, and ventilation fans.

Housed in a rugged NEMA 1 indoor steel enclosure, the timer features teeter-type terminals that facilitate secure connections for both solid and stranded copper conductors. This model serves as the industry-standard direct replacement for 4002-71 and 1102 timer units, ensuring a seamless retrofit into existing power layouts. The integrated manual override switch allows technicians to test or bypass the schedule without disrupting the preset tripper locations, while the high-torque clock motor maintains accurate timing across a wide temperature range from -40?F to 130?F.

• High-Capacity Switching: Rated for 40A resistive and 5 HP at 240V, handling demanding motor and tungsten loads.
• Universal Replacement: Specifically designed to replace legacy 1102 and 4002-71 models without mounting modifications.
• Precision Scheduling: Includes one set of ON/OFF trippers for 24-hour cycle management with support for up to 12 pairs.
• Industrial Duty: Features a lockable gray steel case to protect internal components from tampering and dust.

Common Questions

What is the difference between the Intermatic T101 and T102?
The primary difference is the input voltage requirements; the T101 is designed for 120V applications, whereas the Intermatic T102 wiring is specific to 208-277V systems, typically found in commercial HVAC and lighting circuits.

Can I use this timer for an outdoor pool pump?
The T102 is rated as a NEMA 1 indoor timer. For outdoor installations or pool pump applications exposed to moisture, you should utilize the T102R or T104R versions which feature NEMA 3R rainproof enclosures.

How do I add more than one ON/OFF event per day?
The mechanism supports additional 156T1978A trippers. Simply slide the extra trippers onto the 24-hour dial at your desired intervals to increase daily cycles.
