Three phase four wire voltage protector

The ‌Three-Phase Four-Wire Voltage Protector‌ is a robust, intelligent solution engineered to ensure comprehensive power stability and equipment protection in industrial, commercial, and utility-grade electrical systems. Designed for ‌100A continuous load capacity‌ and ‌690V AC operational range‌, it delivers ‌three-phase + neutral line protection‌ with ‌adjustable overvoltage (260–480V AC)‌ and ‌undervoltage (200–400V AC) thresholds‌, ensuring rapid tripping response (‌<0.1 seconds‌) to mitigate grid fluctuations, phase imbalances, and neutral faults. Its ‌IP66-rated industrial enclosure‌ resists dust, water ingress, vibrations, and extreme temperatures (‌-40°C to +85°C‌), making it ideal for harsh environments.
