2025 Trend Three Phase Adjustable Over and Under Voltage Protector Automatic recovery protective device with reset, rated 63A 380V Key benefits Protects connected equipment by detecting both overvoltage and undervoltage conditions and disconnecting output until safe levels . Adjustable threshold settings let you match protection limits to the needs of different equipment and installations. Automatic recovery with reset reduces manual intervention and helps restore power when line voltage stabilizes, minimizing downtime. Rated for three phase 380V systems and up to 63A continuous current, suitable for medium power circuits. Main features Function: adjustable over voltage and under voltage protection with automatic recovery and reset. Electrical rating: 63A nominal current, 380V three phase application. Compatibility: designed for three phase power distribution and control systems where voltage stability protection is required. Operation: automatic reconnection once voltage returns to the preset safe range, adjustable setpoints to suit different load requirements. Practical applications Industrial motor protection: use on three phase supply lines feeding pumps, compressors, and motors to prevent operation under damaging voltage conditions. HVAC and refrigeration systems: integrate into control panels to protect compressors and control electronics from voltage fluctuations. Commercial and light industrial distribution panels: add as a protective layer for machinery and sensitive equipment in workshops, factories, and small plants. Installation and usage notes Intended for integration in three phase distribution or control panels where 380V nominal supply and up to 63A are present. Adjust threshold settings according to the voltage tolerance of connected equipment to balance protection and availability. Automatic recovery simplifies operation but review settings and wiring during commissioning to ensure correct response for the specific installation. What makes this product stand out Dual direction protection covers both and low voltage events in one device. Adjustable settings provide flexibility for a range of applications without requiring multiple devices. Automatic reset capability reduces the need for manual resets after transient supply disturbances. This device is appropriate for installations that require reliable over and under voltage control for three phase 380V circuits up to 63A.
