T1
General
The T1 breaker family ranges from 15 through 100 amperes. The T1 trip units are
non-interchangeable and use the very latest technology in electromagnetic relays for
overcurrent trip protection. Thermal overload protection is provided by heat sensitive
bimetals. Short circuit protection for the breaker is accomplished using a precise
magnetic coil. State of the art construction in contacts and arcing chambers aid in
limiting damaging fault currents through the protected circuits.
Standards
The UL489/CSA 22.2 version of T1 also carries an IEC-60947-2 rating.
Versions
The T1 frame is available in two versions:
T = Thermal-magnetic, xed
D = Molded case switch
Performance levels
The T1 breaker has two performance levels available:
B = Basic single pole
N = Normal three pole
Number of poles
The T1 molded case circuit breaker is available in single, three and four pole versions.
Estimate 4 pole pricing by adding 35% to the 3 pole price and contact your ABB sales
person for details.
Molded case switches
UL489 switches include no overcurrent protection except for a high instantaneous trip
mechanism for self protection.

General
The Ts3 breaker family ranges from 15 through 225 amperes. The Ts3 trip
mechanisms are non-interchangeable and use sensitive electromagnetic relays for

protection. Short circuit current protection begins at 10 times the thermal rating of
the breaker and uses a magnetic coil principle.
Standards
The UL489/CSA 22.2 version of Ts3 also carries an IEC-60947-2 rating.
Versions
To meet all application needs, the Ts3 is available in various versions:
T =Thermal-magnetic
D = Molded case switch
M = Magnetic only (MCP)
Performance level
Each version is also available in different maximum fault interrupting levels
N = Normal
H = High
L = Extra high
Number of poles
The Ts3 is available in two, three and four pole versions. Estimate 4 pole pricing by
adding 35% to the 3 pole price and contact your ABB sales person for details.
