The ABB TA75DU52/DB80 is a thermal overload relay with a Class 10 trip characteristic, adjustable from 36 to 52 A, and includes the DB80 mounting base for direct connection to ABB contactors in that frame size.
The 36-52 A adjustable range covers motor full-load currents in that band, so the relay is sized to the motor nameplate, not the supply circuit.
