Question 148Electricity & Electronics - 1st Asst/Chief

The correct answer is C) electronic overload relay. The circuit shown in the illustration EL-0091 represents an electronic overload relay, which is a safety device used to protect electrical equipment from excessive current or overload conditions. The relay is designed to detect when the current flowing through a circuit exceeds a predetermined threshold and then disconnect the power supply to prevent damage to the equipment. The other answer choices are incorrect because: A) A voltage regulator is used to maintain a constant output voltage, not to detect overload conditions. B) A function generator is used to generate various waveforms, not to protect against overloads. D) An oscillator is a circuit that generates a periodic signal, not an overload protection device.
