Intermatic T104R Dp O Mechanical Time Switch 208-277V

Product Description

The INTERMATIC T104R DP O is a 24-hour mechanical time switch designed for reliable scheduling of electrical loads in both indoor and outdoor applications. Built on the proven T100 Series platform, this unit operates on 208-277 VAC at 60 Hz and features a double-pole single-throw (DPST) configuration. It is rated to handle up to 40 amps per pole and supports up to 12 ON/OFF operations per day, making it well suited for lighting control circuits and other timed electrical loads. A manual override switch is included for added operational flexibility. The unit ships in a gray metal enclosure rated for indoor and outdoor installation.

This time switch is commonly installed in commercial and residential applications where scheduled lighting control or load switching is required. Typical use cases include outdoor area lighting, indoor lighting panels, and general timing or scheduling tasks. Licensed electricians install this switch as part of branch circuit control systems where automated daily ON/OFF cycles eliminate the need for manual switching. The metal enclosure provides protection in exposed locations such as exterior walls, utility rooms, and equipment areas.
