APW AS-1486500 High Limit Thermostat 550°F

The APW AS-1486500 High Limit Thermostat 550°F is a temperature protection part used in commercial cooking equipment's electrical heating systems. It is mounted within the internal heat-sensing area where a calibrated element responds to excessive thermal accumulation by shifting its electrical state at a defined cutoff point. It is commonly used when cutoff behavior becomes inaccurate or when sensing response drifts from expected calibration. Its sensing interface is aligned to detect rising temperature conditions and initiate an electrical interruption that prevents continued heat escalation within the connected heating path.
