1SDA067428R1

The ABB 1SDA067428R1 is a SACE Tmax XT1N 160 moulded case circuit breaker (MCCB) designed for reliable protection, switching, and isolation in low-voltage electrical distribution systems. It is a four-pole (4P), fixed-mount circuit breaker with front terminals and an integrated TMD thermomagnetic release. The device has a 160 A rated current and a fully rated neutral (InN = 100%), making it suitable for three-phase distribution systems where complete four-pole protection and switching are required. The integrated TMD thermomagnetic trip unit combines thermal overload protection with magnetic short-circuit protection. The thermal protection is adjustable from 112 A to 160 A, while the magnetic release is set at 1600 A.
