New / ExperiencedBuilding on years of experience in supplying

low voltage distribution equipment all over the

world ABB o pens a new a pproach to what a

swi tchboard can b e and how i t can b et ter serve

the user, the des ign engineer and the co ntractor.

Fresh / FamiliarABB builds on the familiar look of a s witchboa rd

with group mounted molded c as e circuit breakers

and fi xed or draw out ma in breakers. Fresh

ideas a re incorporated w ith features such as a

slotted vertica l bus de sign, a full hinged doo r

that incorporates the breaker cover plates, and a

modular frame e nclosure system.

Unique / ReliableUnique design features such as the slotted bus,

and hinged door make this switchboard new.Pla ted copper bus , b ol ted b us connect ions , a

frame enclosure structure, a nd ABB’s proven

breaker technology ma ke this ABB sw itchbo ard

highly reliab le. Qua lity is a sta nda rd fea ture in

ABB sw itchbo ards. A l ist of expens ive optionsis not needed to ensure the highest qua lity

s tanda rds are met.

Features

• Hinged door and large wire ways save t ime a

money in field wiring.

• Unique bus layout delivers the freedom to

locate feeder breakers independent of any hopattern.

• Plated copper bus used in al l three phases an

neutral.

• Cop per ground bus extends full width of

switchboard.

• Horizontal bus up to 5000 Amps

• Vertica l bus up to 3000 Amps

• G roup mounted feeder breakers ranging from

15 amps to 1200 Amps

• Main breakers up to 5000 Amps

• Strong frame construction isolates bus andbreaker ass emblies from enclosure “s kin”. Du

rable dry paint finish. Four inch b as e and liftin

eyes are standa rd.

Switchboard MaxSBGeneral information

5000 amp Mains and 3000

amp vertical bus designs

enable this switchboard to

distribute power in the largest

low voltag e applica tions. A

multi-layered b us d esign a ndmodular enclosure system

provide the flexibility to

provide a n 800 amp free-s tanding sw itchboard tha t

has an extremely small foot

print.

Precise / FlexibleABB ’s switchboa rd uses a frame-bas ed enclosure system. Unlike self-

supporting enclosures the frame supports the bus ba r and breaker as semb lies.

Front panels, s idewalls, and rear panels a re also supported by the frame

structure. This design offers a number of adva ntage s over self-supporting

enclosure systems . Dama ged wa lls and panels can be eas ily replac ed

without the need to disa ss emble interior bus or breaker ass emblies. The

modular nature of ABB’s frame e nclosure system ma kes i t easy to expand

the sw itchbo ard by adding sections as system requirements change. Simply

remove a side wa ll and b utt the new se ction aga inst the old. Overlappinghorizontal bus de sign makes for a simple and ac curate splice c onnection.

Custom / StandardWouldn’t it be nice to have the freedom to layout a sw itchbo ard in such a wa y

that i t compliments the a pplica tion a nd s i te requirements? Would you benefit

from the freedo m to loca te breakers as you cho ose ? Wouldn’t you l ike to ad dcustom fea tures l ike a d ust-proof enclosure, or a full glass doo r for add ed

sec urity and an enha nced appe aranc e in high visibil ity si tes?

ABB’s standard switchboard design makes these and other custom like

features affordab le.

1 15-30A are 65kA at 480VAC

Industrial / CommercialThe Operations Mana ger wa nts reliab ili ty, the s pecifying e ngineer wants a

product he c an b elieve in, the service depa rtment demand s ma intainab ili ty,

the CFO wants value and the contractor wa nts a supplier and prod uct that is

eas y to work with and o n time delivery. One compa ny can ma tch al l of these

requirements; ABB .

The Operations Manag er and s pecifying engineer appreciate features s uch

as plated copper bus and bolted bus connections. A frame-based enclosure

system delivers strength, expa nda bili ty and simplifies repairs. The c ompletesystem is designed a nd tested to meet or exceed UL req uirements.

The maintenance d epartment enjoys a hinged d oor that ma kes i t easy for

qua lified perso nnel to acc ess the c ab inet to maintain and s ervice ABB’s

sw itchbo ards . Connec tions are located so that you can ac tually get to them. A

framed enclosure construction and bus design make this switchboard easy toexpand as requirements change.

Contrac tors save on instal lation time with easy to acc ess terminals, increas ed

cab le area a nd a d esign tha t makes i t easy to add breakers and a ccess or ies inthe field.
