Surge Protective Device 2025 Trend Three Phase Adjustable Over and Under Voltage Protector Overview A three phase voltage protection device designed to detect and respond to both overvoltage and undervoltage conditions. The 2025 Trend model provides adjustable trip thresholds, automatic recovery and reset functionality, and is rated for 63A at 380V. Key benefits Protects equipment from damaging voltage excursions by disconnecting and then restoring supply when voltage returns to acceptable range. Adjustable settings allow tuning of overvoltage and undervoltage thresholds to match system requirements. Automatic recovery and reset reduce manual intervention and help restore normal operation quickly after transient events. Clear rated capacity of 63A at 380V ensures predictable performance in three phase distribution circuits. Main features Function: Adjustable overvoltage and undervoltage detection with automatic recovery and reset. Compatibility: Designed for three phase 380V electrical systems with loads up to 63A. Performance: Rapid response to abnormal voltage conditions while minimizing unnecessary trips through adjustable thresholds. Reliability: Built for continuous use in electrical distribution systems to limit downtime related to voltage anomalies. How it solves common problems Prevents repeated equipment malfunction or damage caused by sustained low or line voltages. Reduces downtime by automatically restoring supply when voltage returns to acceptable range, removing the need for immediate manual reset. Allows of trigger points so sensitive loads are protected without excessive nuisance trips. Typical applications Industrial control panels and motor drives where three phase motors and pumps require protection from voltage fluctuations. Commercial building distribution boards serving HVAC systems, elevators, or lighting circuits that must tolerate temporary voltage variations. Workshop equipment and manufacturing lines where maintaining continuous operation and safeguarding electronic controls is important. What to consider when selecting Confirm three phase system voltage is 380V and load current does not exceed 63A. Set overvoltage and undervoltage thresholds based on the tolerance and sensitivity of connected equipment. Integrate into the distribution panel in line with local wiring practices and applicable installation requirements. Summary The 2025 Trend three phase adjustable over and under voltage protector provides adjustable protection for 380V, 63A systems with automatic recovery and reset. It is suited for industrial and commercial three phase applications where controlled voltage protection and reduced manual intervention are required.
