🔍 Key Concepts

• Location and label of R2 in relation to the CT input, rectifier/diode bridge, and the rest of the timing circuitry • Difference between overload (inverse-time) protection and instantaneous protection in an electronic overload relay • How separate potentiometers in the diagram (R2 vs. the "Inst. Current Setting Pot." and the "Time Delay Setting Pot.") suggest different adjustment functions

💭 Think About

• Trace the current path from the CT input through R2 and the rectifier section: what value or signal would changing R2 actually affect? • Compare what part of the circuit is associated with time delay (look for capacitors and the "Time Delay Setting Pot.") versus what part simply scales the sensed current level. • Why would an overload relay need both an instantaneous setting and a long‑time/overload setting, and which labeled controls in the diagram appear to correspond to each?

✅ Before You Answer

• Identify which component in the diagram is explicitly labeled as the Instantaneous Current Setting Pot. and compare its position to R2 • Check which potentiometer is directly associated with the Time Delay label and timing capacitor(s) and confirm whether that is R2 or a different pot • Confirm whether R2 is in the part of the circuit that shapes the current threshold into the detector, or in the part that shapes the time delay response
