  • Model: 004.014.207
LR2K0307 overload relay 3P 1.2-1.8A
Manufacturer: Schneider Electric
Barcode: 3389110230437
LR2K0307 overload relays are designed for the protection of motors. They are compensated and phase failure sensitive. Resetting can either be manual or automatic.
Direct mounting: under the contactor for versions with screw clamp terminals only.
Separate mounting: using terminal block LA7K0064.
On the front face of the overload relay:
  • selection of reset mode: Manual (marked H) or Automatic (marked A),
  • red pushbutton: Trip Test function,
  • blue pushbutton: Stop and manual Reset,
  • yellow trip flag indicator: overload relay tripped.
