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
