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:
- Monitoring of the residual current in the grounding conductor.
- Voltage monitoring between the transformer neutral and ground.
- 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.

Features
- 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
