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
