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.
