3phase 63A 4pole voltage protector

The 3-Phase 63A 4-Pole Voltage Protector continuously monitors all three phases and neutral for dangerous over-voltage, under-voltage, phase imbalance, and phase loss conditions. When any parameter exceeds safe limits, it disconnects the load within milliseconds to prevent damage to expensive three-phase machinery such as motors, compressors, and industrial equipment. Once voltage returns to normal, it reconnects automatically after a configurable delay. The 63A rating handles substantial commercial and light industrial loads. DIN-rail mounted with an LED display showing real-time voltage readings for each phase, it provides both protection and monitoring in one device.
