IR423 - A-ISOMETER - Insulation monitoring device

General Description

The IR423 A-ISOMETER® monitors 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).

Key Features

  • Insulation monitoring for mobile gene- rators AC 0…300 V.
  • Option “W”: For high mechanical stress when using the protective measure “Protective separation with insulation monitoring and disconnection”.
  • Two separately adjustable response values.
  • Connection monitoring system / earth.
  • Power On LED, LED Alarm 1, LED Alarm 2.
  • Internal and external test / reset button.
  • Two separate alarm relays (one changeover contact each).
  • N / O.
