Frequently Asked Questions

Q: What type of refrigerator compressor is this PTC start relay compatible with?

A: This PTC start relay and overload protector is designed for R600A / 125W mini refrigerator compressors and is broadly compatible with various brands of mini fridges, coolers, and certain air conditioning compressors.
