2�- DESCRIPTION OF THE PRODUCT
The RGU-10 earth leakage relay is type A programmable electronic earth leakage protection
device with two independent relays: the main output for checking the cut off device and perform-
ing the protection function and the pre-alarm relay for installation prevention and maintenance.
Allows the setting and adjustment of all parameters required for complete protection and main-
tenance checking in the installation. A series of parameters may be set directly from the key-
board (buttons) and by setting menus on the device itself.
Before starting the earth leakage device carefully read sections: power supply, connection dia-
gram and setting.
The RGU-10 measures, calculates and displays the earth leakage current in three-phase, bal-
anced or unbalanced industrial systems.
Measurements are in true effective value, via one earth leakage current input, from the WGC
family external measuring toroid.
Under normal operating conditions the main values determining earth leakage protection in an
installation are shown on the display. These include sensitivity, delay and instant current leak-
age.
Bearing in mind the high degree of protection required by installations, the device has a display
