Overload protection is designed to protect the ______ by disconnecting it from the power source when an overload is sensed.

• A. Electric Motor
• B. Control Circuit
• C. Start Switch
• D. Wiring Harness

Answer: (A)

Overload protection is about preventing overheating of the thing that does the work, so it disconnects that device from power when current gets too high. The motor is the load most at risk when overload occurs because excess current causes the windings to heat up, which can degrade insulation or burn the motor. By tripping and cutting power to the motor, the system stops damage and potential fire, while allowing the rest of the control logic to stay intact.

The other parts aren’t the direct target of overload protection in this context. A start switch simply turns the motor on or off; it isn’t designed to protect the device from overheating. A control circuit handles logic and control signals, not the motor’s current protection. The wiring harness could overheat, but protection is typically applied to the motor itself (via a motor starter/overload relay or a circuit breaker) so the critical protected component remains safe and can be shut down immediately.
