The switches are used in secondary medium-voltage power distribution, for example in ring main units, transformer stations, industrial plants as well as in wind turbines and photovoltaic plants. Thanks to the low volume and special design of the devices, switchgear rooms can have narrower dimensions, making them smaller and more cost-efficient. A wide range of connection options to the high voltage contacts gives plant manufacturers optimum busbar mounting options. The circuit breakers are available for different pole distances as well as for left-mounted or right-mounted drives. The single-phase, encapsulated breakers can conduct rated currents of up to 1250 amperes (A) and manage a rated short-circuit breaking current of up to 25 kA. They require no maintenance up to 10,000 electrical switching cycles under normal ambient conditions between -5°C and 55°C.
