Programmable residual current relay, 2 modules with display and static prealarm output

Description

Electronic industrial residual current protection relay, compatible with the WGC series protection transformers.

Ultra-immunised type-A relay, with high-frequency current filtering and high immunity. True root mean square (TRMS) measure.

• Programmable with backlit LCD display:

• Sensitivity and trip time
• Output contact status.
• Protection status messages.
• Real-time level of leakage.

• LED bar showing the percentage leakage current measured by the unit.
• Features two independent programmable outputs (main and prealarm / relay fault).
• Assembly on DIN 46277 rail (EN 50022), 2 modules.
• Locking the programming menu with the keyboard or by sealing the PROG button.
• RCM and MRCD in the same unit (see connections)

Applications

The RGU-2 relays associated with WGC transformers offer smart and robust residual current protection against all types of unwanted tripping. Since these residual current relays only take up 2 modules of space, include an LCD display, a bar LED and are fully programmable, they are essential for protecting people and for preventive maintenance of the installations.
