Industrial 40 A Timer
The Intermatic T104D89 is a heavy-duty DPST timer rated for 40 amps resistive at 208 to 277 volts. It provides direct 24-hour time-switch control for industrial, commercial and residential loads up to 4000 watts.
Scheduling Limits
The mechanism allows one to twelve on/off operations per day with a minimum on or off duration of one hour. Voltage supply must stay within the 208 to 277 volt range for correct operation.
Installation Notes
The unit includes the timer mechanism, a metal case and one on and one off tripper. Wiring must follow the DPST configuration for the rated voltage and amperage. Missing trippers or incorrect voltage will prevent proper switching.

Questions about this item
How many daily ON/OFF operations can the T104D89 timer handle?
The timer supports 1 to 12 ON/OFF operations per day with a minimum interval of one hour between each switching event.
What does the 4000 W rating mean for connected equipment?
At 240 V the 40 A resistive capacity equals 4000 W, so heating elements or lighting loads up to that power can be switched directly.
What voltage range does the DPST timer mechanism accept?
The mechanism operates on 208 to 277 V supplies, covering standard 240 V single-phase and 277 V commercial lighting circuits.
