1SAX211001R1102

ABB 1SAX211001R1102 E45DU-45 Electronic Overload Relay is a self-supplied electronic motor-protection relay designed to protect three-phase motors against overload and phase-failure conditions. Its wide adjustable current range of 15 A to 45 A allows one overload relay to cover multiple motor current ratings while maintaining accurate electronic protection. A major feature of the E45DU-45 is its selectable Trip Class 10E, 20E or 30E, allowing the protection characteristics to be adapted to motors with different starting times and operating requirements. The unit requires no separate external supply for its basic protection function. ABB also specifies temperature compensation, trip-free operation, STOP and TEST functions, trip indication, and selectable manual or automatic reset.
