What is a trademarked device used for compressor overload protection in HVAC systems?

The KLIXON overload protector is a trademarked device specifically designed for providing protection to compressors in HVAC systems from overload conditions. Compressors are vital components that can be susceptible to overheating and electrical failures if they draw too much current due to various issues such as system blockages or mechanical failures. The KLIXON device operates by automatically interrupting the electrical circuit to the compressor when it detects excessive current, thus preventing potential damage caused by overheating.

This type of protection is essential in maintaining the longevity and efficiency of HVAC systems. The KLIXON’s reliability and performance in overload conditions make it a preferred choice among HVAC professionals for safeguarding compressors.

In contrast, thermostats regulate temperature settings and are not specifically designed for overload protection. Capillary tubes are used for refrigerant flow control in the system rather than protecting the compressor itself. Power relays serve as switches that control the circuit but do not offer the same direct thermal or overload protection as the KLIXON device does. This distinction highlights why the KLIXON overload protector is the correct choice when discussing trademarked devices for compressor protection in HVAC systems.
