Description
The Supco L155 is a precision-engineered snap disc auto reset limit switch designed for reliable temperature control in HVAC, appliance, and heating applications. With a fixed 135°F cut-in temperature and a fixed 155°F cut-out temperature, this limit switch provides consistent, repeatable performance to protect equipment from overheating and unsafe operating conditions.
The open-on-rise switch action means the circuit opens when the sensed temperature reaches the 155°F cut-out setpoint, interrupting operation until the temperature drops back to the 135°F cut-in threshold — at which point the switch automatically resets without any manual intervention. This auto-reset functionality minimizes downtime and reduces the need for service calls in standard thermal limit applications.
The snap disc mechanism delivers fast, positive switching action, ensuring accurate response to temperature changes and long-term reliability across many cycles. This switch is a direct replacement for OEM part number 60T11-610010 and is widely used in furnaces, dryers, and other heating equipment requiring dependable high-limit protection.
