Product Details

Description

This premium 2-pole (2P) auto limit switch is a critical safety component designed for HVAC systems and heating equipment. Functioning as a high-limit control, this fan-disc style switch monitors the internal temperature of your appliance to prevent dangerous overheating. If the unit exceeds its safe operating temperature, the switch automatically interrupts the electrical circuit to protect the motor and internal components. Once the system cools down to a safe level, the switch resets itself automatically, ensuring continuous and safe operation. It is a vital replacement part for maintaining the reliability and longevity of residential and commercial climate control units.
