Sale price $ 190.40 Regular price $ 224.00

Therm Coil Drawing No.: 337T-1406-004        Therm Coil Model No: D1-5575-KEP


  • Our D1-5575-KEP heating control has a pilot light and is mounted within a NEMA 1 general purpose enclosure.  It has a temperature range of 200°-550°F, and is rated for 120 to 480VAC.  This control has a tin-zinc alloy-plated (copper) 84" (±2") capillary with a 5/16" DIA. x 4-7/8" (±1") long sensing bulb.  (3x) #8 x 1/2" sheet metal screws for mounting are included.
  •  Application: This non-programmable mechanical DPST thermostat is for heating control only. (This will not work for cooling applications.)
  • ATTENTION!: The default pilot light is rated up to 277VAC.  If you are using the control for voltages above 277VAC, then the pilot light will need to be upgraded - Please contact us at customer.service@thermcoil.com to order!
  • IMPORTANT NOTE: If load amperage or voltage exceeds control rating, a magnetic contactor must be used.
  • Other D1-5575-K Configurations: We also offer other configurations for this thermostat, please click here to quickly see our other model D1-5575-K control options, or contact us if you don't see what you need.

Technical Information

  • Switch Type: DPST (double pole, single throw). A DPST switch turns up to two independent circuits on or off.
  • Switch Action: Normally Closed Contacts Open on Temperature Rise Only.
  • Thermostat Voltage: 120 to 480VAC
  • Pilot Light: Yes: 277VAC MAX.  (contact us if you need a higher voltage pilot light.)
  • Non-Inductive Amperage Rating: See chart below.
  • Minimum Amperage Required: 5 Amps  (When below 5 Amps, the thermostat will not be able to maintain desired temperature reliably, or at all, and may fluctuate wildly in differential.)
  • Themperature Control Range: 200°F to 550°F
  • Maximum Temperature Differential: 22°
