ISOMETER® IR423

ISOMETER® IR423

  • Insulation monitoring device for mobile generators
  • Protective separation with insulation monitoring and disconnection
  • According to IEC 60364-5-55 and IEC 61557-8
  • Two separately configurable response values
  • Multi-functional LC display

The ISOMETER® of the IR423 series is designed to monitor the insulation resistance RF of an unearthed AC system of 0…300 V to earth that is supplied by a mobile generator accor­ding to IEC 60364-5-551 / DIN VDE 0100-551 (VDE 0100-551). The IR423 is suitable for AC sys­tems with operating frequencies ≥ 30 Hz as well as for AC systems with directly connected DC circuits. The maximum permissible system leakage capacitance Cemax is 5 F.
