Key Features

Comprehensive Multi-Dimensional Motor Protection

Adopts accurate I²t thermal model algorithm to realize overload thermal protection. Integrates locked rotor protection, phase unbalance fault protection, ground leakage fault protection, underload abnormal protection, startup overtime protection, overvoltage & undervoltage protection and phase sequence fault protection. All protection thresholds support precise parameter setting to avoid motor winding burnout and mechanical damage.

Precise Real-Time Electric Parameter Metering

Continuously monitors three-phase current, voltage, active power, reactive power, power frequency and electric energy data. Real-time tracks motor operating load status, forms operating trend curves, and provides accurate data basis for motor energy-saving optimization and condition maintenance.

Multi-Point Thermal Temperature Monitoring

Built-in 12-channel RTD temperature acquisition channels, accurately collects stator winding, bearing and cabinet internal temperature data. Issues pre-alarm prompts before overtemperature trip, prevents permanent thermal damage of motor insulation layers.

Fault Waveform & Event Logging Function

Automatically records pre-trip and post-trip current, voltage waveform and switching state data. Stores complete fault occurrence time, cause and operating parameter records. Greatly shortens on-site fault troubleshooting and maintenance diagnosis time.

Stable Industrial Environmental Adaptability

Adopts flame-retardant and corrosion-resistant metal shell, wide temperature operation range, strong anti-electromagnetic interference ability. Runs stably under vibration, dust and humid harsh working conditions of power plants and industrial sites.

Flexible Logic Control & Remote Interconnection

Multiple programmable output contacts realize automatic motor start-stop logic and interlock protection. Supports seamless docking with upper SCADA system through Modbus RTU protocol. Achieves remote status monitoring, parameter modification and fault remote warning.
