AGH676S-4

• Increase of the Isometer’s nominal voltage range
• Used with Isometers of the IRDH… and iso685 series
• For medium-voltage applications up to AC 12 kV

The AGH676S-4 is used for coupling the ISOMETER® IR420-D64 to 12 kV-AC systems in offline mode. Alternatively, the AGH676S-4 can be used in combination with iso685…, IRDH275-4xx or IRDH375-4xx for 12-kV-AC systems in online mode. The coupling device must only be used in combination with the ISOMETER®. All device combinations listed above are not suitable for systems containing converters.
