Intermatic T104P Electromechanical Timer 24 Hour DPST 40A 208-277VAC

SKU CH-K9GP-V5VZS

Electromechanical timer switches 40 A loads on a 24-hour cycle at 208-277 VAC

  • 24-hour scheduling automates daily equipment cycles
  • DPST contact form switches both lines for safe isolation
  • 40 A rating handles heavy motor and heating loads
  • 208–277 VAC input suits commercial three-phase supplies
  • Electromechanical mechanism operates without external control power

Purpose and audience

The Intermatic T104P is a new electromechanical timer designed for 24-hour scheduling of electrical loads. It suits installers and facility managers who need a straightforward DPST switching device rated for 40 amps at 208 to 277VAC.

Fit and alternatives

This timer fits single-phase circuits requiring a 40-amp double-pole single-throw contact that opens both lines simultaneously. Buyers who need multi-day programming, astronomic functions, or digital precision should look at other categories.

Capacity and headroom

The unit handles resistive, inductive, and motor loads up to the 40-amp rating within the stated voltage window. It runs out of headroom when the connected load exceeds 40 amps or when the supply voltage falls outside the 208 to 277VAC range.

Highlights

  • DPST contact form switches both lines for safe isolation
  • 40 A rating handles heavy motor and heating loads

Questions about this item

Do I need a 208-277VAC power source to run this timer?

Yes, the timer requires a supply between 208 and 277VAC to operate its motor and switching mechanism.

Will the DPST contacts replace my existing single-pole switch on the same circuit?

The DPST-NO contact form opens both lines simultaneously, so it can replace a single-pole device only if the circuit uses two hot conductors.

How can I verify the 24-hour dial is keeping time after wiring?

Observe the dial rotation over several hours; it should complete one full revolution every 24 hours when powered.
