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.
