Schneider Electric LRD3361 Overload Relay 55-70A Class 10 3P 690V

Schneider Electric LRD3361 Overload Relay

The Schneider Electric LRD3361 is a thermal overload relay designed to protect three-phase motors from excessive current. It mounts directly onto LC1D65 through LC1D80 contactors and covers a setting range of 55 to 70 amperes. The device operates at up to 690 volts and uses a Class 10 trip characteristic. Manual reset is required after a trip event.

Motor protection for 55 to 70A circuits

This relay suits panels where a 55 to 70 ampere motor starter needs overload protection with a Class 10 response. It fits only the LC1D65 to LC1D80 contactor frame sizes, so installers using smaller or larger contactors must select a different relay. Applications requiring automatic or remote reset should choose another model because this unit resets manually.

Current range 55 to 70A Class 10

The adjustable current range of 55 to 70 amperes combined with a Class 10 trip class is the specification that determines whether this relay matches the motor full-load current and the required acceleration time. Verify the motor nameplate current falls inside this window and that a Class 10 trip curve suits the load before selecting the LRD3361.
