GENERAL FEATURES
The RGU-10 earth leakage relay is type Aprogrammable electronic earth leakage protection equipment with two independent relays 4, the main output for checking the cut off device and performing 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 maintenance checking in the installation. A series of parameters may beset directly from the keypad (buttons) and by setting menus on the instrument itself. Before starting the earth leakage device carefully read sections: power supply, connection diagram and setting. The RGU-10 measures, calculates and displays the earth leakage current in three-phase, balanced or unbalanced industrial systems. Measurements are in true effective value, via one...
