Intermatic T173 Timer

The Intermatic T173 Timer is a heavy-duty 24-hour mechanical time switch engineered for reliable automation in commercial and industrial environments. Featuring a DPST (Double Pole Single Throw) configuration, this 120V mechanical timer is rated for 40 Amp resistive loads per pole, making it an ideal solution for managing high-draw equipment such as HVAC units, pumps, and industrial lighting banks. The defining "Skipper" feature allows contractors to customize schedules by omitting operations on specific days of the week using specialized day-skipper screws.

Designed for professional-grade durability, the Intermatic T173 is housed in a NEMA 1 indoor metal enclosure. The mechanism supports up to 10 ON/OFF operations daily with a minimum interval of one hour, providing precise control over energy consumption. This industrial time switch also includes a manual override lever, allowing technicians to bypass the automated schedule for maintenance or testing without disrupting the primary timing sequence. For seamless integration into existing systems, it utilizes copper conductors and pressure plate terminals to ensure secure, high-conductivity electrical connections.

• High-Capacity Switching: Handles up to 40 Amps per pole, suitable for 2 HP motor loads at 120 VAC.
• Skip-A-Day Flexibility: Allows for omitting scheduled operations on weekends or specific days using the included skipper wheel and screws.
• Rugged Construction: Features a heavy-duty NEMA 1 steel enclosure designed for long-term survival in mechanical rooms.
• Manual Override: Provides a convenient external lever to toggle loads ON or OFF manually without losing the dial position.
• Easy Installation: Equipped with teardrop slots for mounting and standard 1/2-inch and 3/4-inch knockouts.

• Can the Intermatic T173 control a 240V load? The T173 is specifically a 120V clock motor model. For 240V applications requiring the skip-a-day feature, the T174 would be the appropriate 208-277V equivalent.
• How many skipping days can be programmed? The unit includes three skipper screws, though additional screws can be added to skip up to 6 days in a 7-day cycle.
• What wire gauge should I use for a 40A load? To safely handle a 40A resistive load, #8 AWG copper wire rated for at least 90?C is required according to technical specifications.
