2.- DESCRIPTION OF THE PRODUCT
RGU-10 B
is a electronic type B earth leakage current protection and monitoring relay. It has 2
programmables outputs relays: main trip relay and prealarm relay. It has one free voltage input for
external TRIP/RESET.
Allows the setting and adjustment of all parameters required for complete protection and maintenance
checking in the installation.
The
RGU-10 B
measures, calculates and displays the earth leakage current in three-phase, balanced or
unbalanced industrial systems.
Measurements are in true effective value, via one earth leakage current input, from the WG-xx-TB and
WGC-xx-TB families external measuring toroid.
Under normal operating conditions the main values determining earth leakage protection in an instal-
lation are shown on the display. These include sensitivity, delay and instant current leakage.
Under normal operating conditions the backlit display is green. However, after any event causing a
main relay to trip, the backlight is red, indicating the reason.
