Model: 004.030.123
Thermal relay РТН-3353 23…32А
Manufacturer: TDM
РТН-3353 thermal overload relay with possible Imax calibration 23…32А 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.
