24-Hour Time Switch, DPST, 208-277V, Plastic Enclosure, and Pool/Spa Control.
Master your equipment’s energy consumption with the Intermatic T104P3 24-Hour Mechanical Time Switch. This heavy-duty dual-pole single-throw (DPST) timer is the gold standard for reliable, high-voltage control of pool pumps, heaters, and industrial lighting. Housed in a rugged, rust-proof plastic enclosure, the T104P3 is specifically designed to thrive in coastal and high-moisture environments where traditional metal boxes fail. With easy-to-set "trippers," you can automate daily ON/OFF cycles to slash electricity costs while ensuring your pool or spa stays perfectly filtered and ready for use.
Key Features

Warnings and Disclaimers
- High Voltage Danger: This timer controls 240V circuits. Death or serious injury can occur from electric shock. Service must be performed by a [licensed electrician](https://www.intermatic.com).
- Wiring Protocol: Ensure all connections are tight. Loose wires can cause [arcing and fire hazards](https://www.intermatic.com). Verify that the neutral and ground wires are correctly identified.
- Load Compatibility: Never exceed the 40-amp rating. Attempting to run equipment beyond the motor's horsepower rating will result in [premature clock motor failure](https://www.intermatic.com).
- Enclosure Safety: The plastic case must remain closed and latched to maintain its rainproof rating. Do not drill additional holes except at the provided knockouts.
?? Pro-Tips for Success
- Tight Trippers: When setting your ON/OFF cycles, ensure the [brass tripper screws](https://www.intermatic.com) are tightened firmly. If they vibrate loose, the timer will fail to engage, potentially leaving your pool stagnant for days.
- Clock Motor Check: If the dial isn't spinning, check the small "visual motor check" window on the mechanism. You should see the gears moving. If they aren't, verify that you have [power to terminals 1 and 3](https://www.intermatic.com).
- Anti-Freeze Logic: In cold climates, set a second pair of trippers to run the pump for 30 minutes during the coldest part of the night (usually 3 AM) to [prevent frozen pipes](https://www.intermatic.com).
- Manual Override: The silver lever at the bottom left allows you to turn the pump ON for vacuuming without losing your time setting-just remember the timer will eventually "catch up" to the next tripper position.
