This chapter reviews the circuit-breaker designs which are type tested to IEC 60298 and IEC 62271-100 for use on distribution voltages up to 52 kV. The design and service experience of different types of commercially available circuit-breakers are considered. The chapter also discusses some special switching duties and focuses on aspects which are necessary for the selection of circuit-breakers for various duties: for example, for switching capacitor banks, capacitive and inductive currents, generators, reactors and synchronised switching of transformers with reactors on the secondary side.
