This limit switch is engineered to protect HVAC equipment from unsafe temperature conditions by interrupting the circuit when the fixed close temperature of 125°F is reached. Once the system cools to the 100°F open temperature, the auto reset function restores normal operation without manual intervention. The green color coding allows technicians to quickly distinguish this switch from other limit controls during installation, inspection, and maintenance.
