ABB SACE Tmax XT1B Moulded Case Circuit Breaker – 160A Frame, 160A TMD, 4-Pole with Fully Rated Neutral (1SDA066821R1)

Ensure ultimate protection for your low-voltage distribution systems with this ABB SACE Tmax XT1B molded case circuit breaker. This high-performance 4-pole device features a fixed design with front terminals for straightforward installation and a thermal-magnetic (TMD) trip unit offering an adjustable overload setting (112-160A) and a fixed magnetic short-circuit trip set at 1600A. Featuring a fully rated neutral (InN=100%), this breaker provides complete protection across all four poles, making it ideal for systems with high neutral currents such as those with non-linear loads, harmonics, or single-phase circuits. With a breaking capacity of 25 kA at 240V AC and 18 kA at 415V AC, along with compliance to IEC 60947-2 standards, it delivers maximum protection for feeders, motor circuits, and industrial control panels. Rated for both AC and DC applications (up to 500V DC) with a mechanical durability of 25,000 cycles and an insulation voltage of 800V, this 4-pole breaker ensures safety, reliability, and operational continuity in the most demanding environments.
