3 pole, 125 amps rated at 480V AC and 500V DC, Tmax molded case circuit breaker with a thermal magnetic trip device and 25kA at 480V AC interrupt current rating
Modified Industry Description
BKR T3N 125A 3P T/M
ABB Tmax T3N125TW Normal Interrupt Molded Case Circuit Breaker, 600 VDC, 125 A, 25 kA Interrupt, 3 Poles, Thermal Magnetic Trip
The T3 breaker family ranges from 60 through 225 A. 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 10X 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.
