Why Choose the ABB T4V 320 TMA 320-3200 3P F F Circuit Breaker?

The ABB 1SDA054269R1 is a high-performance SACE Tmax T4V moulded case circuit breaker (MCCB) designed for reliable protection and switching in demanding industrial and commercial low-voltage electrical distribution systems. As part of the established ABB SACE Tmax T4 series, this three-pole circuit breaker combines a 320 A rated current with a TMA thermomagnetic trip unit for dependable overload and short-circuit protection.

The TMA release provides thermal overload protection together with adjustable instantaneous magnetic short-circuit protection. Its magnetic trip setting range of 1,600–3,200 A allows short-circuit protection to be coordinated with the requirements of the protected circuit, helping safeguard cables, switchgear and downstream electrical equipment against damaging fault currents.

With a 320 A rated current, three-pole construction, fixed installation and front terminals, the T4V 320 TMA 320-3200 is designed for straightforward integration into low-voltage switchboards and distribution panels. The V short-circuit performance level is intended for demanding installations requiring particularly high fault-current interruption capability.

High-Performance Protection for Power Distribution

Moulded case circuit breakers such as the ABB SACE Tmax T4V protect electrical distribution circuits against overloads and short circuits while also providing a practical means of switching and isolation. The TMA thermomagnetic release combines thermal protection for sustained overload conditions with adjustable magnetic protection for rapid interruption of severe short-circuit faults.

The 320 A rating makes the 1SDA054269R1 suitable for higher-current feeders and three-phase distribution circuits. Its adjustable 1,600–3,200 A instantaneous magnetic trip range provides flexibility when coordinating protection with cables, downstream equipment and other protective devices, while the V performance level is designed for installations where high prospective fault currents demand strong interruption performance.

Typical Applications

  • Industrial low-voltage power distribution systems.
  • Three-phase feeder circuit protection.
  • Main and sub-distribution switchboards.
  • Higher-current industrial distribution circuits.
  • Manufacturing and process plant electrical systems.
  • Commercial and infrastructure power distribution.
  • Industrial machinery and production facilities.
  • Installations with high prospective short-circuit currents.
