ISOMETER® isoGEN423

  • Insulation monitoring device for mobile generators
  • Protective isolation with insulation monitoring and shutdown
  • In Accordance with DIN VDE 0100-551 and DIN EN 61557-8
  • Two Response values (Factory settings 46 kΩ, 23 kΩ)

The ISOMETER® monitors the insulation resistance of unearthed AC, AC/DC and DC systems (IT systems) with nominal system voltages of 3(N)AC, AC/DC 0…400 V or DC 0…400 V.

The maximum permissible system leakage capacitance Ce is 5 μF. DC components existing in AC systems do not influence the operating characteristics, when a minimum load current of DC 10 mA flows. A separate supply voltage allows de-energised systems to be monitored, too.
