STATS-06 3-Phase 4-Wire Over/Under Voltage & Current Protector with Multi-Protection

Three-phase systems fail in more ways than single-phase ones, and a single protection function is rarely enough. The Soltree STATS-06 is purpose-built for AC380V 3-phase 4-wire circuits — integrating six protection functions into one DIN rail device: over-voltage, under-voltage, over-current, phase loss, open neutral, phase sequence error, and 3-phase unbalance detection. When any of these faults occur, the STATS-06 trips immediately, disconnecting the load before equipment damage occurs. Once the fault clears, it automatically restores power after the configured recovery delay.

The high-definition color display shows real-time voltage and current for all three phases simultaneously — current values below 1A are suppressed to keep the display clean and readable. All protection thresholds are field-configurable: over-voltage from 230–300V (default 270V), under-voltage from 120–210V (default 170V), over-current from 1–63A or 1–100A, plus adjustable action time and recovery delay. A built-in 3-phase voltage and current calibration function corrects measurement errors at installation, ensuring accuracy throughout the device's service life.

Widely deployed in photovoltaic energy storage systems where 3-phase unbalance is a common fault mode, industrial distribution panels protecting motor-driven equipment, commercial building power supplies where phase loss could damage HVAC compressors, and any application where a single-function protector leaves too many failure modes uncovered. Available in white or dark gray housing, supports custom LOGO for OEM integration, and backed by a 3-year warranty.
