Separate Switch Disconnector enclosure

fiftyhertz
Morning All, 


Why would you use a separate switch disconnector enclosure ie Schneider SEA9PNI2504, the vast majority of distriubtion boards i see have an incomer device at the base of the busbar, which could also be used as a protective device. Never really understood why a separate unit would be required?


Is there a practical reason im missing.


Thanks

    The practical reason is that the 250A switch is too big so requires a separate enclosure. The standard Acti9 boards, although the busbar is rated at 250A, only have the physical capability to have a 125A 4P switch in the conventional position. So when you need more capacity you have to fit the separate extension enclosure. It has all the links to join it to the busbars in the kit of that number you mentioned Fiftyhertz
