What is a Klixon?

A Klixon refers to a specific type of thermal overload switch used in electrical applications, notably in air conditioning and refrigeration systems. Its primary function is to protect compressors from overheating by breaking the electrical circuit when a preset temperature threshold is exceeded. This is crucial in preventing damage to the compressor, which is often one of the most critical and expensive components in an HVAC system.

In the context of air conditioning, a Klixon is vital for maintaining the health and efficiency of the system by ensuring that the compressor does not operate under harmful conditions. When the compressor overheats due to prolonged operation or insufficient cooling, the Klixon will activate, interrupting the power supply and allowing the unit to cool down before it can restart safely. This protective feature helps enhance the longevity and reliability of the equipment, making the Klixon an essential component in compressor assemblies.

While there are other components and functionalities in HVAC systems related to safety and pressure control, the distinctive role of a Klixon as an overload protector specifically highlights its importance in safeguarding compressors from thermal damage.
