Function and operation of switchboards

ABB Switchboards are designed to integrate circuit breakers, fuses, metering, surge protection, and other electrical products to distribute and monitor power safely. By definition, an electric switchboard is a device that distributes electricity to several smaller load circuits. It is an assembly of one or more panels, each containing switching devices for the protection and control of circuits fed from the switchboard. Busbars are added inside a switchboard. What is a busbar? Flat strips of copper or aluminum are insulated to help carry large currents that connect the switchgear.

In a modern switchboard, the operator is protected from electrical injury by metal-enclosed circuit breakers, switches, and fuses.

ABB provides an extensive offering of switchboards used in industries such as:

With switchboard offerings such as group mounted, generator connection, individually mounted, and metering, the ABB switchboard portfolio has the product for your switchboard application needs.
