Product identity

The Intermatic 24-Hour Time Switch is a single-pole electromechanical timer rated for 120 V AC and 40 A. It suits residential or light-commercial loads such as pumps, fans or lighting circuits that need daily on/off control.

Bundled trippers

Two trippers are included in the package, allowing up to twelve on/off cycles per day. Extra trippers are available separately under part number 2E054 for installations that require more switching points.

Installation checks

Verify the supply voltage is between 110 V and 125 V AC and that the load does not exceed 40 A or 2 hp at 120 V. The NEMA 3R steel enclosure with grey enamel finish is rated for outdoor use, so confirm the mounting location provides the required clearance for the 5 1/2 in width, 3 5/8 in depth and 9 7/16 in height. Buyers needing a multi-pole timer or a different voltage rating should look elsewhere.
