Model: 004.030.090

Manufacturer: Schneider Electric

Barcode: 3606480325311

EasyPact TVS thermal overload relay LRE481 with possible I_max calibration 62...99A 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.
