The panels, that are mainly used to control the powers are called PCC panels. The sizes of the panels depends upon the amount of current it handles.
Almost all types of  industries requires these types of the panels. The switchgears may be Air circuit breakers ( ACB ) OR Molded Case Circuit Breaker ( MCCB ) OR Switch Disconnector Fuse unit (SDF).
Most of the time, the panels and the breakers inserted  inside them must be by the same manufacturer. Each manufacturer has one or more “systems”, or kinds of breaker panels, that will only accept breakers of that type. In Europe, this is still the case, despite the adoption of a standard DIN rail for mounting and a standard cut-out shape, as the positions of the busbar connections are not standardized.
