🔍 Key Concepts

• Refrigeration compressor safety devices that act before a relief valve lifts • Difference between pressure control switches (cutout switches) and relief valves • Which device responds to abnormally high discharge pressure in the system

💭 Think About

• Which component is designed to sense system pressure and shut off the compressor motor before any mechanical overpressure protection is needed? • Does a relief valve act electrically or mechanically, and does it stop the compressor or just vent pressure? • In normal operation, would an operator rely on low pressure, back pressure, or high pressure to protect against overpressure before the relief valve opens?

✅ Before You Answer

• Identify which option is a control that stops the compressor rather than venting pressure • Match each cutout switch name (low, back, high) with the part of the system it protects (suction vs discharge side) • Confirm that the chosen device is intended to act before the relief valve lifts as the primary overpressure protection
