Description
The Supco SRL230 SPST M/R Rollout Switch is used to detect excessive heat conditions and interrupt burner operation when temperatures reach 230F, protecting heating equipment from damage caused by flame overheating. It operates by opening the electrical circuit once the preset temperature threshold is exceeded, preventing continued system operation under abnormal conditions. Frequently integrated into residential, commercial, and industrial HVAC systems, including furnaces, unit heaters and gas-fired heating equipment, this switch is mounted near the burner compartment for direct thermal monitoring. Its operation supports improved safety response, dependable equipment protection, and stable heating system performance during operating conditions.
