These circuit breakers are of live tank design. They are used in power distribution for control and protection of lines and for control and protection of transformers, rectifier units, capacitor banks, etc. Thanks to the autopuffer breaking technique, they do not generate operating overvoltages. This means they are also highly suitable for retrofitting, where the plant insulating materials may be sensitive to dielectric stresses.
