Intermatic T7802B Timer

The Intermatic T7802B is a heavy-duty 7-day mechanical time switch engineered for precision scheduling in demanding commercial and industrial environments. This 208-277V timer features a 2 NO/2 NC (DPDT) contact configuration, allowing for the simultaneous control of up to four separate circuits or complex multi-load switching. With a robust 40 Amp resistive rating per pole and the ability to handle motor loads up to 10 HP at 240V 3-phase, it is a reliable choice for HVACR equipment, industrial lighting, and irrigation pumps.

Designed for maximum field flexibility, the T7802B includes separate clock motor terminals. This architecture enables the clock to run on designated line voltage while switching independent loads that may operate on different voltages. The mechanical dial supports 7-day programming with a minimum 3.5-hour ON/OFF interval, accommodating unique schedules for each day of the week. Housed in a NEMA 1 steel enclosure, this unit provides a rugged solution for indoor installations requiring consistent, high-capacity timing.

• Multi-Circuit Control: The 2 NO/2 NC contacts provide versatile wiring options for complex DPDT applications.
• Industrial Capacity: Rated for 40A per circuit, making it suitable for high-wattage lighting banks and heavy machinery.
• Independent Clock Terminals: Allows for switching loads not on line voltage, increasing compatibility with various control circuits.
• 7-Day Customization: Supports different daily schedules to optimize energy consumption across varying weekday and weekend operations.
• Manual Override: Features an integrated lever for manual switching without disrupting the programmed 7-day cycle.

Can the clock motor and the load operate on different voltages?
Yes, because the unit features separate clock motor terminals, you can power the timer mechanism at 208-277V while switching a secondary load voltage, provided it stays within the 40A contact rating.

What is the minimum interval I can set for a cycle?
The mechanical trippers allow for a minimum ON/OFF time of 3.5 hours, which is ideal for preventing short-cycling in heavy motor and HVAC applications.

Does this unit retain time during a power outage?
This specific T7802B model is a standard electromechanical switch without a battery carry-over. In the event of a power failure, the dial must be manually reset to the current time of day once power is restored.
