Intermatic T104R 24-Hour Timer Switch – DPST, 208–277VAC, Outdoor

Precise, durable scheduling for lights, pumps, fans, and HVAC

The Intermatic T104R 24-Hour Mechanical Timer Switch delivers dependable, hands-off control for a wide range of loads. Built to endure, its heavy-duty outdoor enclosure protects internal components from the elements while providing reliable cycling across two lines with a DPST design. This timer makes routine automation feel effortless, letting you set a daily rhythm for essential equipment without continuous monitoring.

With a straightforward, mechanical timing mechanism, you get 1 to 12 “On/Off” operations per day and minimum On/Off times of one hour. The result is predictable, repeatable behavior that can adapt to your site’s routine—whether you’re managing exterior lighting, a circulating pump, or a small HVAC accessory. The model’s 208–277 VAC compatibility ensures it handles typical commercial and residential power setups with ease, while the manual override adds a quick, tactile way to adjust on the fly.

Rugged design built for real-world use

The outdoor-rated Type 3R metal enclosure is designed to stand up to weather exposure, dust, and routine wear. The timer’s high current rating—up to 40 amps—supports a broad range of equipment, including motors often found in commercial settings. Engineers and facilities teams alike can appreciate the robust build that minimizes downtime and maintenance needs.

• DPST contacts enable independent control of two circuits, delivering versatility for combined loads like lights and pumps.
• Capable of handling motors up to 5 HP at 240V and 2 HP at 120V, making it suitable for many applications.
• Simple, reliable 24-hour scheduling that operates without a continuous power draw for control logic.

Real-world use cases you can envision

Set lights to illuminate after dusk, cycle a fountain pump during off-peak hours, or automate a ceiling fan or ventilation damper. The timer’s tactile override lets you bypass the schedule for quick adjustments, while its punchy, mechanical action provides a tangible sense of control.

• Ideal for storefronts, outdoor signage, pools, and irrigation systems requiring repeatable daily cycles.
• Suitable for HVAC accessories and pumps where two-line control improves system coordination.

In short, the Intermatic T104R is about predictable timing and durable, field-ready performance. It offers a practical mix of reliability, ease of use, and rugged construction, helping you automate essential loads with confidence without overpromising results.
