24-Hour Electromechanical Timer
The Intermatic T1906 is a 24-hour electromechanical timer rated for 20 A at 208 to 277 V AC. It uses a single-pole double-throw contact form with a steel NEMA 1 enclosure. The unit provides up to 48 on/off cycles per day with a minimum setting of 15 minutes. It suits industrial or commercial lighting and motor control circuits.
Upgrade From Basic Time Switches
This timer replaces simpler on/off switches that lack multi-operation scheduling or day-skipper flexibility. The jump is worth it when you need 96 included trippers for complex daily patterns or a 1 hp motor rating at 240 V. It is not for buyers who want astronomic programming, battery backup, or multi-voltage auto-sensing in a single device.
Straightforward Surface Mounting
Installation uses the steel enclosure’s mounting ears for surface attachment to a junction box or panel. Wiring connects to screw terminals rated for the 20 A load. What usually goes wrong is forgetting to remove the appropriate knockout for conduit entry or exceeding the 23-3/4 hour maximum dial setting. Extra trippers are available as part 2E132.
