What type of response does an electronic overload relay typically provide upon detecting an overload?

An electronic overload relay is designed to protect motors from excessive current conditions, which can lead to overheating and damage. When an overload situation is detected, the relay monitors the current flowing to the motor, and upon identifying that the current exceeds the pre-set threshold for a specific duration, it responds by shutting down the motor.

This immediate disconnection helps to prevent further damage to the motor windings and other related components by stopping the motor from operating under harmful conditions. The shutdown response is a critical safety feature that ensures the longevity of the motor and prevents potential hazards, such as fire.

Options that suggest increasing power supply, altering the motor speed, or reconfiguring the motor wiring do not align with the primary function of an overload relay, which is exclusively to provide protection through motor shutdown. Therefore, the correct response of shutting down the motor is essential for maintaining safe operation and preventing equipment failure.
