BBBB
Combination of Multi-CB units
Application Scenarios
Suitable for main distribution networks or terminal power supply systems.
Applicable to cities, residential areas, commercial zones and industrial parks.
Can be installed in distribution rooms, package substations and outdoor switch cabinets. Meets the requirements of new construction, renovation and various other projects.
Core Features
Capable of breaking short-circuit currents, isolating various faults locally to minimize outage areas.
Protection relays can be fitted on every unit or installed only on outgoing units. Either self-powered protection or integrated protection (requiring an external power supply) is available as an option.
Expandable design with capacity upgrade potential. For example, a combination can be extended from 4-units to 5-units combination.
