Modular phase control relays are designed to protect electrical equipment and consumers in case of power supply network quality violations. They perform continuous voltage monitoring in single-phase and three-phase AC networks, disconnecting equipment with a specified time delay when voltage goes outside the range, as well as monitoring the correct phase sequence, loss of one or more phases, and the neutral.
