York S1-025-27792-009 Open Switch Rollout Manual Reset 350°F

The York S1-025-27792-009 Open Switch Rollout is a safety switch to prevent HVAC equipment from overheating. It has a Manual Reset button that immediately opens when the temperature inside the system rises to 350°F. Possible harm to the distal equipment is avoided enabling the equipment to function optimally. Equipment life is increased, maintenance costs are decreased, and system performance is improved. The switch on the sidebar trips whenever it senses that the system is getting too hot and shuts down the power supply to the HVAC system until the cause of overheating is addressed and the control circuit resets the switch. This goes a long way to preventing expensive rectification and time losses that result from overheating of equipment.
