Intermatic T101 Indoo 24-hour Mechanical Time Switch 120V

Product Description

The INTERMATIC T101 INDOO is a 24-hour mechanical time switch designed for indoor electrical load control in residential and commercial applications. Operating at 120 volts AC, 60 Hz, it features a single-pole single-throw (SPST) configuration housed in a gray metal enclosure built for indoor installations. The switch supports up to 40 amps per pole and allows up to 12 ON/OFF operations per day, giving electricians and facility maintenance professionals precise scheduling control over lighting circuits and other timed loads. A manual override switch is included for on-demand control without disrupting the programmed schedule. The T100 Series platform is a long-established line known for reliable mechanical operation.

This time switch is suited for indoor lighting control, scheduling, and general ON/OFF timing applications in residential and light commercial settings. Typical installations include controlling exterior lighting circuits fed from indoor panels, managing HVAC auxiliary loads, pump timers, and similar scheduled-operation equipment. The metal enclosure provides durable housing appropriate for utility rooms, mechanical rooms, and similar indoor environments where a robust enclosure is required.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize the circuit at the breaker panel and verify with a meter before handling any wiring. The enclosure should be mounted securely to a wall or panel surface in a dry indoor location. Confirm load amperage does not exceed the 40-amp-per-pole rating before energizing.
