Coupling devices AGH675S-7/AGH675S-7MV15 series Product description The coupling devices of the AGH675S-7/AGH675S-7MV15 series are used to extend the nominal voltage range of the ISOMETER® IRDH275BM-7 illustrated in the wiring diagram. The ISOMETER® IRDH275BM-7 together with the coupling device AGH675S-7 monitors the insulation resistance of IT medium voltage systems up to 7,2 kV. The ISOMETER® IRDH275BM-7 together with two coupling devices AGH675S-7MV15 monitors the insulation resistance of IT systems up to 15,5 kV. Always two AGH675S-7MV15 together with one IRDH275BM-7 are required. Terminal...
