Mechanical Time Switch · 208-277 VAC · DPST 24-Hour 40A Indoor Enclosure · Intermatic T104
SKU: T104
24-hour electromechanical time switch for 208-277 VAC control circuits with DPST switching and a 40A rating. Commonly used to automate lighting, pumps, water heaters and other fixed loads where a simple repeat daily schedule is needed.
What this product is for
The Intermatic T104 is a 24-hour mechanical time switch used to automatically turn connected loads on and off on a repeating daily schedule. It is designed for 208-277 VAC, 60 Hz applications and uses a DPST switching arrangement in an indoor metal enclosure.
Use for
Use for lighting control, pumps, fans, water heaters, signage and other fixed equipment that benefits from scheduled operation. This style of timer is commonly selected where electricians want simple mechanical scheduling without programming menus or network controls.
Avoid for
Avoid for applications needing digital programming, holiday scheduling, astronomic functions or short interval switching below the unit's 1-hour setting increments. Also avoid where an outdoor or washdown-rated enclosure is required unless a suitable enclosure variant is specified.
Best for
Best for commercial, industrial and service replacement work where a proven 24-hour dial timer is preferred for straightforward daily load control. It is also a practical choice for replacing existing T100-series 208-277 VAC DPST mechanical timers.
Installed in
Typically installed in electrical rooms, mechanical rooms, service areas, plant spaces and indoor utility locations. The enclosure is NEMA 1 indoor type, so it is intended for dry indoor installations.
Why this product exists
This product provides a simple way to reduce unnecessary run time on connected equipment by switching loads automatically each day. For lighting and similar loads, scheduled shutoff is a typical way to reduce wasted energy and operating hours.
Compared with similar products
Compared with digital time switches, the T104 offers simpler setup and familiar field serviceability. Compared with single-pole timer models, this DPST version switches two poles, making it suitable for 208-277 VAC applications that require double-pole control. As a rule of thumb, mechanical timers like this are often chosen when reliability and quick replacement matter more than advanced scheduling features.
