1SAX111001R1101

ABB 1SAX111001R1101 E16DU-0.32 Electronic Overload Relay is a compact electronic motor-protection relay designed to protect three-phase motors against overload and phase-failure conditions. It has an adjustable current setting range of 0.10 A to 0.32 A and provides selectable 10E, 20E and 30E trip classes, allowing the protection characteristics to be adapted to different motor starting times and applications. The E16DU is self-supplied, so it does not require a separate external control power supply for its basic overload-protection function. It monitors the motor current electronically and provides reliable tripping when prolonged overload or phase-loss conditions are detected. The relay includes 1 normally closed and 1 normally open auxiliary contact, enabling contactor tripping together with alarm, PLC feedback or remote fault indication.
