AGH520S

• Increase of the Isometers' nominal voltage range
• Used with Isometers of the IRDH… and iso685 series
• For medium-voltage applications up to AC 7.2 kV

The coupling device AGH520S is designed to extend the nominal voltage range of the ISOMETER® iso685… series and IRDH275-4…/IRDH375-4…/IR470LY-40/IR420-D6/IRDH1065B-4 to (3)AC 0…7200 V, 50…400 Hz.
The coupling device is connected to the system to be monitored by one pole and connected to the terminal AK of the ISOMETER® by means of the terminal 5.
