Product Description
Main Feature:
-
Temperature Monitoring
- Constantly measures motor winding temperature through embedded sensors
- Detects abnormal heat rise patterns (≥Class B insulation limit of 130°C)
-
Overheat Prevention
- Triggers instantaneous shutdown when:
- Continuous operation exceeds FLA (Full Load Amps)
- Cooling system failure occurs
- Ambient temperature surpasses 40°C (104°F)
-
Bimetal Disc Protection
- Utilizes calibrated bimetal strips that deform at preset temperatures:
- Typically trips at 105°C±5% for standard compressors
- Auto-resets when temperature drops below 70°C
-
Motor Protection
- Prevents:
- Insulation breakdown (Dielectric Strength >2.5kV)
- Bearing grease carbonization
- Rotor demagnetization in VFD-driven units
-
Diagnostic Feedback
- Provides NC/NO contact signals for PLC integration
- LED indicators for:
- Trip status (Red)
- Reset readiness (Green)
