Key Features

1. Comprehensive Motor Protection
   • Electrical fault protection: Overload, short circuit, ground fault, overvoltage, undervoltage, unbalanced current, undercurrent.
   • Mechanical fault protection: Mechanical jam, stall, reverse rotation, RTD overtemperature, startup failure.
   • Thermal protection: Adaptive thermal model to prevent overheating during prolonged operation or frequent startups.
2. Precision Metering & Monitoring
   • Real-time monitoring of voltage, current, power (kW/kVAR/kVA), energy, frequency, and power factor.
   • 12 RTD inputs for stator winding, bearing, and ambient temperature monitoring.
   • Startup data logging: Captures current, voltage, and temperature profiles during motor startup.
3. Advanced Diagnostics & Analysis
   • Event Logging: Stores up to 512 time-stamped events (alarms, trips, self-tests).
   • Waveform Capture: Triggers 3 waveform records during trips, capturing 16 data cycles of phase/ground current and contact status.
   • Motor Health Reporting: Analyzes historical data to predict maintenance needs and identify potential faults.
   • Pre-Trip Alarms: Issues early warnings for ground faults, jams, or overtemperature before tripping.
4. Flexible Communication & Integration
   • Multi-port communication enables connection to SCADA systems, PLCs, and PCs.
   • Compatible with EnerVista 369 software for remote configuration, monitoring, and data retrieval.
   • Supports custom programmable logic for application-specific control requirements.
5. Robust & User-Friendly Design
   • Wide-range control power (50–300 VDC / 60–265 VAC) for global deployment.
   • DIN rail mounting for easy installation in control panels.
   • Flame-retardant, corrosion-resistant metal enclosure for harsh environments.
   • Intuitive LCD/keypad for local parameter adjustment and fault diagnosis.
