1SAX321001R1101

ABB 1SAX321001R1101 E140DU-140 Electronic Overload Relay is a self-supplied electronic motor protection relay designed to provide reliable protection for three-phase motors against overload and phase-failure conditions. Its wide adjustable current range of 50 A to 140 A allows one relay to cover several motor ratings while providing precise electronic overload protection. The E140DU-140 offers selectable Trip Class 10E, 20E or 30E, allowing the trip characteristic to be matched to motors with different starting times and load conditions. It is self-supplied, so no separate external power supply is required for its basic protection function.
