A _____ is sometimes required to indicate when a motor has stopped due to an overload trip?

• A. Indicator light
• B. Alarm signal
• C. Buzzing sound
• D. Remote send

Answer: (B)

When a motor trips due to an overload, it’s essential to alert someone that a fault has occurred and why. An alarm signal provides a clear, noticeable notification that the motor stopped because of an overload, prompting quick action to check, reset, or repair. A simple indicator light may show that the motor isn’t running, but it doesn’t convey the cause of the stop, which can lead to confusion or delays. An audible alarm, or a combined alarm signal, is a more reliable way to ensure the message is noticed in a busy control room or noisy environment. A remote send is for off-site monitoring and isn’t the immediate on-site indication needed in this situation.
