Schneider 3MZ2-WRDUWZ | Protection relay, EOCR Digital, 0.5 to 60A, 100 to 240VAC/DC, window connt, for motor protection

Description

The Schneider Electric EOCR Digital Protection Relay is an electronic motor protection device designed to provide reliable monitoring and protection for electric motors against abnormal current and operating conditions. It supports a current setting range from 0.5 to 60A and operates with a wide 100–240VAC/DC control supply, making it suitable for a broad range of industrial motor-control applications. The window-type current sensing design allows the motor conductors to pass directly through the relay for practical and compact current monitoring.

The EOCR Digital range is designed to help protect motors against conditions such as overload, phase loss, phase imbalance, locked rotor, short circuit, and earth fault, depending on the relay configuration. Digital monitoring and trip-cause indication help operators identify faults quickly and reduce troubleshooting time.

Its electronic design provides accurate motor-current supervision while offering easy configuration and reset options for motor protection systems. Schneider Electric lists manual, electrical, and automatic reset capabilities within this EOCR Digital platform.
