The TA75DU42 is a thermal bimetallic overload relay rated for 42 A, adjustable down to 29 A. Selectable manual or automatic reset gives you field flexibility: auto for unattended pumps, manual for conveyors where you want a positive reset after a fault. This is a 3-pole NEMA-style unit from the ABB A-Line family. It mounts directly to A/AE/AF50 through A/AE/AF75 frame contactors, so if you're rebuilding a panel that uses those contactors, this relay bolts on without adapter plates or extra wiring. The thermal bimetal element is field-replaceable — no shop, no crane, fix it where it sits.
