Description
The Intermatic T173 is a heavy-duty mechanical time switch built for reliable, automatic on/off control of lighting, HVAC, pumps, motors, and other electrical loads. Designed for commercial, residential, and light-industrial environments, this timer offers robust capacity, a flexible “skip-a-day” feature, and a durable build for consistent, maintenance-free scheduling.
Key Features
-
High load capacity (40 A, DPST, 120 VAC): Capable of handling resistive, inductive, tungsten loads — suitable for motors, heaters, lighting banks, pumps, and more.
-
Flexible scheduling — 24-hour dial with skip-a-day option: Allows up to 10 ON/OFF operations per day, with the ability to skip selected days using included “skipper” screws — ideal for schedules that don’t require daily operation.
-
Minimum 1-hour ON/OFF intervals: Practical for applications like lighting, HVAC, water heaters, or any system where hourly scheduling is sufficient.
-
Manual override switch: Provides manual control when needed — useful during maintenance or when bypassing the automated schedule temporarily.
-
Durable indoor-rated metal enclosure (NEMA 1): Built to last, with operating temperature range from –40 °F to 130 °F. Wall-mountable — good for indoor utility closets, mechanical rooms, or wiring panels.
-
Straightforward mechanical design: Uses a simple dial-and-tripper system — no programming, no batteries — just reliable, mechanical timing you can trust.
