Air-insulated switchpanels from ABB ABB s ZS8.4 range is designed to provide maximum flexibility and the highest possible safety for circuit-breaker systems or switch-disconnector installations, using either conventional instrument transformers or modern sensor technology. Developed to meet the specific needs of medium voltage switchgear users in every respect, ZS8.4 delivers perfect power distribution. A strong solution for every market Customers throughout Europe rely on ABB s ZS8.4 family of air-insulated switchgear to provide the ideal, flexible solution for virtually any application. 2 ZS8.4 Air-insulated medium voltage switchgear

3 Simply universal Flexible safe economical The main scope of application for ZS8.4 switchgear has, in recent years, shifted increasingly to the primary distribution level with circuit-breakers. It is an independent product line targeted at the interface between secondary and primary distribution level. The majority of ZS8.4 installations are for industrial customers, however it is also specified for power supply and municipal services applications. In a wide range of situations, including metros, shopping malls, manufacturing facilities and offices ZS8.4 with vacuum circuitbreaker, switch-disconnector or vacuum contactor is the costeffective route to ensuring a safe and reliable power supply. Today there is an installed base of more than ZS8.4- panels in Central Europe, Asia and the Gulf States, with the majority found in Germany. ZS8.4 combines mature, well-established switchgear technology with modern manufacturing processes to deliver the optimum costeffective solution. ABB s ongoing product development process has resulted in the addition of a contactor panel as well as panels with expanded automatic protection against accidental contact.

4 Details in focus With comprehensive interlocks and integrated protection against accidental contact with the busbars, ZS8.4 offers a unique safety concept. For example, mutual interlocking of the devices practically precludes maloperation. Maintenance-free switching devices and the sealed encapsulation ensure permanently reliable operation. 4 ZS8.4 Air-insulated medium voltage switchgear

5 Automatic protection against accidental contact: By shutter in panels with tee-off partitioning, and by sliding plate in panels without tee-off partitioning. Three function areas are mutually partitioned - low voltage area, busbar area and MV area with circuit-breaker area, switch-disconnector area, contactor area and cable termination area.
