3 pole, 20 amps rated at 600V AC, Tmax molded case switch with thermal magnetic fixed trip device and 22kA at 480V AC interrupt current rating
Modified Industry Description
BKR T1N 20A 3P T/M UL
ABB T1N020TL Tmax Normal Interrupt Molded Case Circuit Breaker, 600 VAC/500 VDC, 20 A, 22 kA Interrupt, 3 Poles, Thermal Magnetic Trip
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.
