🔍 Key Concepts

• Trace how the GP supply feeds the control relay, fuses, and indicator lights in the lower part of the diagram. • Identify what the 10 amp fuses (P5 and P6) actually protect and whether they are in series with the motor power or only with pilot/indicator circuits. • Note how the overload relay contacts (P3–P4) and the control relay (CR) control the "Run" and "Overload" indicator lamps.

💭 Think About

• If the motor is already running, which components must stay energized for it to continue running: the 440 V power circuit, the line contactor coil, or the indicator circuits? • Follow the circuit path from the GP supply to the motor: does that path pass through either of the 10 A fuses, or do the fuses only affect the pilot lights? • Consider separately what happens if the fuse feeding the "Run" lamp opens versus the fuse feeding the "Overload" lamp. Which answer choice matches the effect of losing either of those fuses while running?

✅ Before You Answer

• Verify whether the line contactor (LC) coil and overload relay still have power if a 10 A fuse opens. • Confirm that the 440 VAC 3‑phase motor circuit (L1, L2, L3 through LC and OL to M) is completely independent of the 10 A fuses. • Check exactly what each 10 A fuse (at P5 and P6) feeds: the Run light, the Overload light, and whether any safety indication would be lost if its fuse were blown.
