EasyPact TVS thermal overload relay LRE489 394...630A

Model: 004.030.098
Thermal relay LRE489
Manufacturer: Schneider Electric
EasyPact TVS thermal overload relay LRE489 with possible Imax calibration 394...630A and class 10A is designed to protect AC circuits and motors against:
  • overloads
  • phase failure
  • long starting time
  • prolonged stalled rotor condition
The thermal relay controls permanently the current driven by the motor. When this current exceeds the setting it's auxiliary contacts will change state, causing the motor to stop.
