Schneider Electric EOCR3DE-05DUH | 0.5-7A Digital Motor Protector 100-240V AC/DC
Schneider Electric EOCR3DE-05DUH electronic motor relay. 0.5-7A range, True RMS sensing, 100-240V AC/DC supply. Protects against overload, phase loss, and stall. Through-type (DUH) design for DIN rail.
Product Overview
The Schneider Electric EOCR3DE-05DUH is a digital electronic motor protection relay from the EOCR-3DE series. It provides comprehensive protection for three-phase and single-phase motors in the 0.5–7 A current range. Featuring True RMS current measurement and a 100–240 V AC/DC wide-range power supply, this "through-type" (DUH) model is designed for direct DIN rail mounting with motor cables passing through the unit, eliminating the need for external current transformers (CTs) in standard applications.
