Enclosures 1447A K122 and 1447AL122 accept a 200 A switch only.This switch will not fit in any other1447A Series Enclosure. Order AllenBradley 1494F-L4 door hardware for1447A K122 and 1447A L122enclosures.
FinishDoor and enclosure arephosphatized and finished in ANSI/ASA 61 gray recoatable powdercoating on the outside.Enclosure interior is finished in whitepowder coating.Inner panel is finished in whitepowder coating.
ApplicationDesigned to house Allen Bradley1494F flange mounted disconnectswitches and 1494D flange mountedcircuit breaker operators (will notaccept Allen Bradley 1494Vdisconnect switches).Provides a degree of protection fromfalling dirt, dust, oil and water.
