Description
The Supco LD120 is a precision-engineered snap disc temperature limit switch designed for dependable over-temperature protection in a wide range of HVAC and appliance applications. With a fixed 105°F cut-in temperature and a fixed 120°F cut-out temperature, this auto-reset device responds quickly and consistently to temperature changes, helping safeguard equipment without requiring manual intervention after a trip event.
The SPDT (Single-Pole, Double-Throw) switching configuration provides versatile circuit control, making it suitable for both normally open and normally closed wiring arrangements. The snap disc mechanism delivers fast, positive switching action that minimizes contact arcing and ensures long service life even under repeated thermal cycling.
