A low voltage relay is an electrically operated switch that uses a small control voltage (typically below 1000V AC or DC) to switch larger electrical loads on and off. These relays act as intermediaries between control circuits and power circuits, providing isolation, control, and. Undervoltage protection plays a major role in keeping electrical equipment safe from damage caused by low voltage conditions. Motors, generators, transformers, and other industrial loads are designed to operate within a specific voltage range. Under voltage is a fault condition in the power system which damage the system equipment such as alternators, generators, transformers, etc. What controls it: Relay performance depends on the protected zone, CT/PT inputs, pickup settings, time delay, breaker clearing time, trip.
