Supco L205 Snap Disc Auto Reset Temperature Limit Switch
The Supco L205 is a precision-engineered snap disc temperature limit switch designed to protect HVAC and appliance systems from dangerous overheating conditions. With a fixed cut-in temperature of 165°F and a fixed cut-out temperature of 205°F, this auto-reset control provides dependable, repeatable thermal protection without the need for manual intervention after a trip event.
How It Works
The L205 utilizes a snap disc mechanism that opens the circuit on a rise in temperature — activating at 205°F to interrupt the circuit and protect downstream components. Once temperatures drop back to the 165°F cut-in threshold, the disc automatically resets and restores normal operation. This open-on-rise, auto-reset action makes it ideal for applications where continuous monitoring and automatic recovery are essential.
