RC48N

The RC48N ground-fault neutral-grounding monitor is used to monitor high-resistance grounded installations. The maximum ground fault current in these systems is limited by a neutral grounding resistor to 5 A, 15 A or 25 A .

The RC48N ground-fault neutral-grounding monitor combines three functions in one device:

  1. Monitoring of the residual current in the grounding conductor.
  2. Voltage monitoring between the transformer neutral and ground.
  3. Monitoring of the grounding resistor for continuity (NGR).

If a value is not within the thresholds, a relay with two voltage-free changeover contacts will be activated.

Caractéristiques

  • Ground-fault monitor for high-resistance grounded installations with a limited fault current of 5 - 25 A
  • Three-in-one functionality: Residual current, voltage and grounding resistor continuity
  • Measures the residual current by means of a Bender residual current transformer
  • Alarm easily recognizable by LED lights
  • Alarm relay with adjustable trip time
  • Measures resistance value and voltage drop of the NGR via coupling devices
  • Alarm easily recognizable by LED lights
  • The alarm relay can be used for the tripping of a load switch
  • Depending on the type of load switch the operating mode of the alarm relay can be set to N/O operation or N/C operation

Applications

  • High-resistance grounded installations with a limited fault current of 5…25 A
  • Mining applications
