The RC48C ground-fault ground-c ontinuity monitor is used to monitor the residual current in high-resistance grounded instal- lations. The maximum ground faul t current in these installations is limited by a neutral grounding resistor to 5 A, 15 A or 25 A.

It is particularly suitable for monitoring cables. The RC48C ground-fault ground -continuity monitor combines two functions in one device:

  1. Monitoring of the residual current and
  2. Monitoring the grounding conductor for low resistance, high resistance and shorted.

If a limiting value is exceeded, a relay with two voltage free chan- geover contacts will be activated. Alarm messages of the RC48C ground-fault ground-c ontinuity monitor can also be displayed on a remote RI2000GC alarm indicator and operator panel.
