Therm-O-Disc Snap-Action Capillary Controls 10H Series

The 10H series temperature control from Therm-O-Disc was originally developed to sense hot spots along the length of electric baseboard heaters. It is also used in electric baseboard heaters , commercial dishwasher and other HVAC applications. where it is necessary to sense temperatures along a continuous length.

The 10H features include:

 ? The ability to sense temperature along a continuous length. 

? Excellent sensitivity. Since the capillary tube is charged, the 10H responds to the hottest spot along the capillary tube. 

? High-speed contact separation for long contact life. 

? Design flexibility provided by a variety of switch actions, capillary tube lengths, mounting brackets and terminations

The 10H is available in two switch actions: 

Automatic Reset (Type 10H11) – SPST contacts open on temperature rise and automatically reset on temperature fall.

Manual Reset (Type 10H14) – SPST contacts open on temperature rise and can be reset when the control has cooled to a lower temperature and the reset button has been depressed. The 10H manual reset is agency recognized as an “M1 trip free” construction, which means that if the reset button is held down, the control can cycle thermally.

Terminal Characteristics

The 10H can be calibrated to open on temperature rise between 150°F (65.6°C) and 350°F (177°C), with a standard tolerance of ±15°F (±8.5°C). The 10H automatic reset will reclose the contacts at approximately 40°F (22°C) below its open temperature. Manual reset controls may automatically reset when exposed to temperatures below -31°F (-35°C).
