ABB 1SDA067446R1 XT1S 160 TMD 160-1600 4p F F InN=100% 4-Pole 160A Fixed Moulded Case Circuit Breaker

The ABB 1SDA067446R1 XT1S 160 TMD 160-1600 4p F F InN=100% is a 4-pole, 160 A fixed moulded-case power circuit breaker from the Tmax XT1 series, engineered for transformer, generator, and installation protection in demanding industrial environments. Featuring a thermal-magnetic TMD trip unit with a current setting range of 160–1600 A and 100 % neutral conductor protection (InN=100%), this breaker delivers precise overload and short-circuit protection across all four poles. Its compact fixed design — just 101.6 mm × 130 mm × 70 mm and 1.4 kg — makes it ideal for space-constrained switchgear panels and distribution boards.
