ABB 1SAZ321201R1006

ABB 1SAZ321201R1006 is the TA75DU-80 thermal overload relay that provides motor protection in ABB control gear by pairing with A50–A75 contactors, monitoring current in the main circuit and tripping when an overload or phase fault is detected. It is rated for a nominal current range of 60 to 80 A and carries a Class 10A trip characteristic, delivering dependable protection for medium-sized motors while minimizing nuisance tripping during startup or transient conditions. Designed to slot into ABB's TA75 family and used with contactors in the A50–A75 series, this relay provides compact, economical overload protection for motor circuits and is intended to integrate with ABB's broader motor-control solutions. The 1SAZ321201R1006 part number identifies the device unambiguously as ABB's TA75DU-80 thermal overload relay, a standard component in motor-control assemblies that safeguards the main circuit from overload and phase-loss events.
