Product Description
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
- High-Voltage Performance: Specifically rated for 208V to 277V applications, making it ideal for powerful commercial and residential pool pumps.
- Rugged Plastic Enclosure: The Type 3R non-metallic case is UV-stabilized and rainproof, providing superior corrosion resistance in salt-air or chemical-heavy environments.
- DPST Configuration: Features a Double Pole Single Throw switch, allowing you to disconnect both "hot" wires simultaneously for increased safety and equipment protection.
- 24-Hour Automation: Includes one set of ON/OFF trippers for a daily schedule, with the capacity to hold up to 12 pairs for complex timing needs.
- Manual Override: A built-in manual lever allows you to turn equipment on or off instantly without disrupting your pre-set automated programming.
- Industrial Durability: Features a high-torque, heavy-duty motor and clock dial designed for decades of continuous operation.
- Simple Installation: Equipped with multiple knockouts and a clear internal layout to ensure a fast, clean setup for pool professionals and electricians.

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.
- 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.
