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 for high-resistance grounded installations with a limited fault current of 5…25 A
- Measures the residual current by means of a Bender residual current transformer
- Alarm easily recognizable by LED lights
- Alarm relay with two voltage free changeover contacts
- Alarm contact delayable by a selectable time
- Recognizes series resistance faults and cross resistance faults
- 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
