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
