7-Day 2-Channel Timer

The Intermatic ET1725C is an electronic timer designed for industrial electrical control and automation. It provides two independent channels with SPST and DPST contact forms for switching loads up to 30 amps across 120 to 277 volts AC.

28-Event Programming Limit

The timer stores up to 28 on/off events, with each on/off action consuming two events. Minimum setting resolution is one minute and the maximum schedule spans seven days, while a two-second pulse duration option supports brief activation needs.

Replaces Mechanical Time Switches

This unit upgrades from mechanical time switches that lack battery backup and multi-channel flexibility. The three-year battery backup retains programming during power loss, and the metal NEMA 1 enclosure suits surface mounting in protected indoor environments.

Questions about this item

Should I pick the 7-day or 24-hour version for a weekly lighting schedule?

The ET1725C is a 7-day electronic timer, so one unit covers a full weekly cycle without needing a separate 24-hour model.

How does the 30 A rating translate when I wire a 120 V motor load?

At 120 V the contacts are rated for 1 HP, which typically draws well under the 30 A resistive limit, so the timer handles the motor directly.

Does the 120-277 V range mean it works on both single-phase and three-phase panels?

The timer is rated 120-277 V AC for single-phase supplies; three-phase voltages are outside the listed range.
