Three Phase Over Under Voltage Protector, 230V 63A Adjustable Automatic Reset, DIN Rail Mount, Voltage Display, TOVPD3

Product Details ①. Over and Under Voltage Protection: Instantly cuts off power during over/under voltage to prevent electrical equipment damage; automatically restores power when voltage returns to normal, avoiding equipment failure due to voltage fluctuations and extending lifespan. ②. Real-time Voltage Monitoring: Equipped with voltage display function to measure and monitor circuit voltage in real time, helping users track electrical status and detect potential issues promptly. ③. Multi-scene Protective Functions: Integrates phase unbalance, phase sequence (reverse phase), break circuit, and phase failure protection to comprehensively safeguard against various circuit faults, reducing outage risks. ④. Adjustable Parameters: Over/under voltage thresholds and action times are adjustable (default settings pre-configured), allowing customization for different circuit requirements with simple operation. ⑤. Easy DIN Rail Installation: Designed for 35mm DIN rail mounting, saves space and integrates seamlessly into existing electrical systems, suitable for professional electricians or DIY installation.
