General Layout Information (Type SB1, SB2, SB3, IPS)Panel Mounted MCCB — 400A through 1200AIPS service sections can house botha main service disconnect device andbranch disconnects. Switchboardscan be furnished with “Suitable forUse Only as Service Equipment”labels, but include no provisions forutility metering.Branch circuit device unit space varies,depending on the rating and consequentphysical size of the main disconnectdevice. If more unit space is requiredthan is shown in the tables below, oneor more additional panel mounted devicedistribution sections must be added.KK400-1200A Main Breaker Without GFPLConduit AreaTop or BottomL400 -1200A Main Breaker With GFPKKLConduit AreaTop or BottomL12 SWITCHBOARDSM C BUnitSpaceHUnitSpaceHM/BGFWDWDFig. 1 Top Entrance (Invert for bottom entrance)Fig. 2 Bottom Entrance (Invert for top entrance)Main Breaker with or without Ground Fault ProtectionDimensions in inches (mm)Max.

(254 mm) of unit space. See page 12-12 for unit space requirements for disconnect devices. Available unit space for 400 and 600 amp main breaker sections is reduced to53.75 if load side through bus is required. Optional section depths are 20", 28" and 38". Optional 70" high is also available. Unit space is reduced by 20". 46 in. (1168 mm) wide if 750 kcmil or compression lugs required.Siemens Power Distribution & Control, SPEEDFAX 2007-2008 Product Catalog 12-9
