ABB 1SDA067423R1 XT1N 160 TMD 80-800 4p F F 4-Pole 80A Fixed Moulded Case Circuit Breaker

The ABB XT1N 160 TMD 80-800 4p F F (SKU: 1SDA067423R1) is a 4-pole, 80 A fixed-mount power circuit-breaker from the Tmax XT1 series, engineered for reliable overload and short-circuit protection of transformers, generators, and distribution installations. Featuring a TMD (Thermal-Magnetic Device) trip unit with an adjustable current range of 80–800 A, this compact MCCB delivers robust performance in demanding industrial environments. Its fixed execution and compact footprint — 101.6 mm × 130 mm × 70 mm — make it ideal for space-constrained control panels and switchboards.
