Abstract
An improved motor protection switch incorporates a parallel feedback component mounted in parallel to a heater in a motor protection circuit. The parallel feedback component senses the temperature of a compressor component. If tie temperature increases then the current flow through the heater increases. This causes a motor protector switch to open. In this way, the feedback component provides feedback from the compressor pump unit to the motor protection circuit more quickly than in the prior art.
