aluminum (Cu/Al) lugs are no charge
when or dered with breaker.
General
The S3 breaker family ranges from 15 through 225 amperes. The S3 trip
mech a nisms are non-interchangeable and use sen si tive elec tro mag net ic relays
for overcurrent trip pro tec tion. Heat sensitive bimetals are used for ther mal
over cur rent protection. Short circuit cur rent protection begins at 10 times the
ther mal rating of the breaker and uses a magnetic coil principle.
Versions
To meet all application needs, the S3 is available in various versions:
T =Thermal-magnetic
Q =100% UL rated
D = Molded case switch
M = Magnetic only (MCP)
G = 3X Mag (100 - 225A 3-pole only)
Performance level
Each version is also available in different maximum fault in ter rupt ing levels
B = 240VAC
N = Normal
H = High
L = Extra high
Number of poles
In UL/CSA form, the S3 is avail able in two pole or three pole versions, both with
the same dimensions. A four pole ver sion is also available in UL/ IEC form. For
price estimate, add 35% to list price of selected version three pole breaker,
contact ABB Control for details.
Accessory mounting
Internal accessories are UL/CSA ap proved for both factory or fi eld installation.
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.
Reverse feeding
All versions of the S3 family are suitable for reverse feed applications.
Molded case switches
UL489 switches in clude no overcurrent pro tec tion except for a high in stan ta neous
trip mech a nism for self protection. IEC type molded case switches with no trip
pro tec tion are also available.

Note: When applied cor rect ly, 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 con tin u ous 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.
