🔍 Key Concepts

• Low pressure cutout switch function in a refrigeration system • Relationship between suction (evaporator) pressure and system load/demand • Difference between protective devices (safety) and control devices (automatic cycling)

💭 Think About

• Is the low pressure cutout primarily there to protect the compressor from damage, or to control when it runs based on system load? • How does evaporator (suction) pressure change when there is little or no cooling demand? What should the compressor do in that situation? • Which option describes a normal, repeated operating action, and which options describe an emergency or abnormal protection function?

✅ Before You Answer

• Identify which choices describe continuous automatic control vs. emergency protection only • Think about what happens to suction pressure when the desired box/space temperature is reached • Verify which answer most directly matches the idea of cycling the compressor on and off as the evaporator pressure rises and falls
