Undervoltage Three Phase Voltage Monitoring Relay 5 LED Lights For Status Indication
All electric appliances are very sensitive when using the grid voltage is too high too low, whether industrial equipment or household appliances have a rated voltage, the voltage range is usually specified as 170V-240V (can be seen on the nameplate or instructions of the electrical equipment). If this voltage is exceeded, the insulation strength and pressure resistance of the electric appliance are exceeded, and the electric appliance will thus generate heat, breakdown and burn or even cause a fire. At present, due to the theft of the zero line, aging equipment, technical failures, human failures, natural disasters, power outages, and other reasons, the voltage instability, the voltage is too low, resulting in a large number of electrical appliances are burned out and burned in large areas, People have suffered heavy losses, no claims, and labor and people’s misfortune have come one after another. Yimin’s overpressure, overpressure, and undervoltage protectors (also known as electrical protectors) should be added to prevent electrical fires and protect the safety of lives and property.
■Features:
