Circutor Has designed the relay of differential protection RGU-10, of reduced size and visualisation of the current of escape by means of display.
It incorporates also regulation of the sensitivity and of the retardo, two relays of independent and programmable exit, and the possibility of communications RS485 MODBUS.
His main applications are the protection and signaling in front of currents of defect to earth, improve the preventive maintenance and realise a fast location of defects.
Also it integrates the current of defect to earth in the system of energetic control and realises a control of the isolation of the installation.
