Earth-leakage monitoring relay RGU2

ACDIN railIEC

Electronic industrial earth leakage 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) 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.
