S7
General
The S7 breaker family is a 1200A frame utilizing a mi cro pro ces sor based
overcurrent pro tec tive trip sys tem. In the 1200A version, the trip unit is adjustable
from 480A up to 1200A without the addition of any parts or rating plugs. As
standard, the S7 includes adjustable long time func tion for overload protection
and ad just able in stan ta neous func tion for short circuit protection.
Versions
To meet all application needs, the S7 is available in various versions:
B = Adjustment LI
C = Adjustment LSI
E = Adjustment LSIG
Q = 100% UL rated
D = Molded case switch
M = Magnetic only (MCP)
Trip functions
These tripping functions are avail able:
L = Long time I = In stan ta neous
S = Short time G = Ground fault
Performance level
Each version is also avail able in different maximum fault in ter rupt ing levels
H = High
L = Extra high (IEC only)
Number of poles
15
In UL/CSA version, the S7 is available as in two pole or three pole version, both
with the same dimensions. A four pole version is also avail able in a UL/IEC form.
For price estimate, add 35% to list price of selected three pole, contact ABB
Control.
Accessory mounting
Internal ac ces so ries are UL/CSA approved for both factory or fi eld in stal la tion.
Accessories require control ca ble con nec tors. Shunt trips or UVR's mount in the
left cavity. Auxiliary or bell alarm switches mount in the right cavity.

UL 100% rated
When applied correctly, UL tested 100% equipment rated breakers may be
applied at full rating rather than on the sizing rules of the NEC where breakers and
cable are sized based on actual continuous load current divided by 80%. This
100% rating can save the user the cost of larger cable or bus bar. Please consult
the NEC for details and other design factors needed for this application.
