1SDA054240R1 ABB T4L 250 TMA 160-1600 4P F F Moulded Case Circuit Breaker 160 A

Why Choose the ABB T4L 250 TMA 160-1600 4P F F Circuit Breaker?

The ABB 1SDA054240R1 is a high-performance SACE Tmax T4L moulded case circuit breaker (MCCB) designed for dependable protection and switching in industrial and commercial low-voltage electrical distribution systems. Part of the established ABB SACE Tmax T4 series, this four-pole circuit breaker combines the T4 250 frame with a 160 A TMA thermomagnetic trip unit.

The TMA release provides thermal overload protection together with adjustable instantaneous magnetic short-circuit protection. Its magnetic trip setting range of 800–1,600 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 overcurrents.

With a 160 A rated current, four-pole construction, fixed installation and front terminals, the T4L 250 TMA 160-1600 is designed for straightforward integration into low-voltage switchboards and distribution panels. The T4L performance level provides an ultimate short-circuit breaking capacity of 120 kA at 400 V AC, making this MCCB particularly suitable for demanding installations with high prospective fault currents.

Reliable Circuit Protection for Power Distribution

Moulded case circuit breakers such as the ABB SACE Tmax T4L protect electrical distribution circuits against overloads and short circuits while also providing a practical means of circuit switching and isolation. The TMA thermomagnetic release uses thermal protection for sustained overload conditions and magnetic protection for rapid interruption when severe short-circuit currents occur.

The four-pole configuration makes the 1SDA054240R1 suitable for distribution systems requiring four-pole circuit interruption, while the adjustable 800–1,600 A instantaneous magnetic trip range provides flexibility when coordinating protection with the electrical installation. Its high T4L breaking capacity makes it particularly suitable for industrial switchboards and distribution systems where substantial prospective fault currents may be present.
