More Documents- A distribution board is a type of electrical cabinet that is installed right in the MSB cabinet and is a source cabinet from which to distribute branch loads. The DB switchboard can be installed as wall mounted with a rated current of up to 400A and as vertical with a rated current of up to 800A.
- The cabinet is installed with measuring and protection devices for the main purpose of switching and protecting the entire load system.
- The electrical cabinet is designed in the form of a box or a module, in which the switchgear, functional modules, and busbar system are arranged aesthetically and reasonably to facilitate the installation at the construction site and the lifting. level as well as the operation of the user unit. The rated current of the DB cabinet depending on the load characteristics can be up to 800A according to IEC 61439.
- DB electrical cabinets are often used in constructions: Industrial, Factory, Commercial Center, Building, Apartment,…
