Description

This electronic industrial residual current protection relay is compatible with WGC series protection transformers. It is an ultra-immunized type-A relay with high-frequency current filtering and high immunity, featuring true root mean square (TRMS) measurement.

Programmable with Backlit LCD Display

• Sensitivity and trip time adjustments
• Output contact status display
• Protection status messages
• Real-time leakage level display
• LED bar indicating the percentage of leakage current measured

Main Features

• Two independent programmable outputs (main and pre-alarm/relay fault)
• DIN 46277 rail (EN 50022) assembly, 2 modules
• Menu locking via keyboard or PROG button seal
• RCM and MRCD functionality in the same unit

Applications

RGU-2 relays combined with WGC transformers provide smart and robust residual current protection, preventing unwanted tripping. With only 2 modules of space, an LCD display, a LED bar, and full programmability, these relays are essential for protecting people and performing preventive maintenance on installations.
