This Burnham Commercial safety device is designed to prevent overheating in various heating systems. The component, known as a thermal link, operates at a maximum temperature of 318 degrees Celsius. When this temperature is exceeded, the thermal link interrupts the electrical circuit, effectively shutting down the system to prevent damage or fire. This specific model is compatible with a range of Burnham Commercial heating systems and is designed for easy installation and replacement. It's constructed from durable materials to ensure longevity and reliability in demanding environments.
