What is an Overload Protector?

An overload protector is a safety device designed to prevent damage to electrical appliances, such as air conditioners, by interrupting the flow of electricity when the current exceeds safe levels. In HVAC systems, this device protects sensitive components like compressors from overheating or drawing excessive current. Without an overload protector, the risk of system failure or fire hazards significantly increases.

How Does Part Number 331213a8.000 Work?

The overload protector, part number 331213a8.000, monitors the electrical current flowing to the compressor in your RV’s air conditioning system. When the current exceeds the preset limit due to overload or a malfunction, the device interrupts the circuit, safeguarding your equipment. Once the issue is resolved, the protector resets, restoring normal operation.
