13 / 81 page ![]() 10 ABB AC1615S - 03/10 T3 T3 225A, 600Y/347VAC, 480VAC ∆ Thermal-Magnetic T3 General The T3 breaker family ranges from 60 through 225 amperes. The T3 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 begins at 10 times the thermal rating of the breaker 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 C22.2 No. 5 version of T3 also carries an IEC-60947-2 rating. Versions The T3 frame is available in three versions: T = Thermal-magnetic, fixed M = Magnetic only (MCP) D = Molded case switch Performance Levels The T3 breaker has two performance levels available: N = Normal S = Standard Number of Poles The UL/CSA version of the T3 is available in three and four pole versions. IEC versions of the T3 are also available with the same dimensions up to 250 amperes. Please contact ABB for details. Molded Case Switches UL/CSA switches include no overcurrent protection except for a high instantaneous trip mechanism for self protection. Reverse Feeding All versions of the T3 family are suitable for reverse feed application.
