SPECIAL VARIANTS
of the
Extensive Range of RCCBs
The following types of standard RCCBs
can be manufactured with a range 
of special variations.
Some examples of these are shown here.

Type 'AC' Range  
For use in 50Hz AC electrical circuits 
feeding loads which do not interfere with
the standard AC supply.

Type 'A' Range    
For use in 50Hz AC electrical circuits 
feeding loads which can generate pulsed
wave forms on the AC supply.
	
Type 'B' Range      
For use in 50Hz AC electrical circuits 
feeding loads which can generate AC & DC
leakage currents
