RGU2, Residual current relay
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.
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.
