What is the characteristic of a Class K connector?

Used for high-voltage applications
Fireproof and flame-resistant
Designed for quick disconnect
Low-profile design

The correct answer is: Fireproof and flame-resistant

A Class K connector is specifically designed to have fireproof and flame-resistant characteristics. This feature is essential in applications where there is a risk of exposure to high temperatures or flames, ensuring that the connector can withstand such conditions without degrading or failing. The construction of a Class K connector typically includes materials and designs that help prevent combustion and resist thermal damage, which is crucial for maintaining safety and reliability in electrical systems, especially in aviation and aerospace applications where fire hazards can pose significant risks. Other options may not accurately describe the defining features of a Class K connector. For instance, while connectors used in high-voltage applications might need unique materials, the defining trait for Class K focuses on fire resistance rather than voltage or quick disconnect capabilities. Similarly, while connectors with low-profile designs are valued in various applications for space efficiency, this characteristic does not apply to Class K connectors as a classification feature.
