This high-limit thermal switch is an essential safety component designed for HVAC systems and commercial air handling units. Operating as a fan disc-style control, this switch is engineered to open at 200°F, effectively cutting power to the heating circuit to prevent equipment overheating and ensure safe operation. If your heating system is shutting down prematurely or experiencing safety circuit interruptions, this 200-degree thermal limit may require replacement. It provides reliable protection against excessive heat buildup, safeguarding both the appliance and the surrounding environment. This durable thermal cutout is a common requirement for maintaining the performance and safety of furnaces, air handlers, and rooftop HVAC units.
