The AAON R72200 (L300-20F) limit switch is an OEM safety control device. It functions as a high-limit temperature safety cutoff that trips at 300°F to break an electrical circuit and prevent HVAC heating element overheating. Normally closed (NC) circuit configuration that opens automatically when temperatures reach the 300°F threshold to cut power to the heat source, preventing fire or equipment damage.
Specifications
Part Number: R72200
Model Type: L300-20F (300°F rating with a 20°F differential)
Design/Housing: Enclosed (ENC) style with a compact 0.75-inch insertion length profile.
Weight: ~1.00 lb
Reset Type: Automatic reset once the sensed temperature drops safely below the reset differential threshold.
