For motors with a rated current between 95 … 120 A, the Schneider LRD4367 is the matching TeSys LRD thermal overload relay, Class 10A, with 1 NO + 1 NC auxiliary contacts.
Set the dial to the full-load current on the motor nameplate. The NC contact (95-96) goes in series with the contactor coil and the NO contact (97-98) can signal the trip to a lamp or PLC input.

Compatibility and replacement
For separate mounting on a rail or plate Schneider offers a terminal block adapter (LAD7B106 for LRD01-35). If the motor current is near the top of the range, use the next range up so the setting sits mid-scale.
Frequently asked questions
How do I reset it?
Use the blue reset button; manual or automatic reset is selected on the relay.
Which contactors does it fit?
Per Schneider: LC1D150, LC1D115.
Can it be mounted separately from the contactor?
Yes, with the Schneider terminal block adapter for independent mounting on a rail or plate.
What current range does it cover?
95 … 120 A, set on the front dial.
