SRL130 Supco THERMOSTAT MANUAL RESET Rollout
SRL130 Supco THERMOSTAT MANUAL RESET
Crosses to Copeland Comfort Control (White Rodgers) 3L12-130
The Supco SRL130 is a 130°F manual‑reset safety thermostat designed for dependable protection in furnaces, heaters, and HVAC equipment. This SPST, open‑on‑rise limit interrupts the circuit when temperatures reach 130°F, preventing overheating or flame rollout conditions. Once tripped, the SRL130 requires a manual reset, ensuring a technician inspects the system before operation resumes.
Built with a durable bimetal disc and compact form factor, the SRL130 is a direct replacement for many OEM rollout and high‑temperature safety switches, including the Copeland / White‑Rodgers 3L12‑130 family.
