RC48C
The RC48C ground-fault/ground-continuity monitor is used to monitor the residual current in high-resistance grounded installations. The maximum ground fault current in these installations is limited by a neutral grounding resistor to 5 A, 15 A or 25 A.
It is particularly suitable for trailing cable protection. Trailing cables are very susceptible to environmental damage and therefore they need special attention. This is where BENDER comes in.
The RC48C ground-fault/ground-continuity monitor combines two functions in one device:
- Monitoring of the residual current and
- Monitoring the grounding conductor for low resistance, high resistance and shorted.
If a limiting value is exceeded, a relay with two voltage free changeover contacts will be activated. Alarm messages of the RC48C ground-fault/ground-continuity monitor can also be displayed on a remote RI2000GC alarm indicator and operator panel.

Features
- Ground fault monitor with integrated loop monitoring
- Measurement of the fault current by means of a Bender measuring current transformer
- Alarm easily recognisable by LED lights
- Alarm relay with two voltage-free changeover contacts
- Alarm contact can be delayed by a selectable time
- Detection of series and transverse resistance faults
- The alarm relay can be used to trigger a load switch
- Depending on the type of load switch, the operating mode of the alarm relay can be set to normally open or normally closed operation
Applications
- Monitoring cables that feature a pilot wire
- Monitoring of earthing systems
