Why Choose the ABB T4V250 TMA 200-2000 1SDA054259R1 Circuit Breaker?
The ABB 1SDA054259R1 is a high-performance SACE Tmax T4V 250 moulded case circuit breaker (MCCB) designed for reliable protection and isolation of low-voltage electrical distribution systems. Configured as a fixed four-pole breaker with front terminals, it combines a 200 A rated current with ABB's TMA thermomagnetic trip unit for dependable overload and short-circuit protection.
Part of the proven ABB SACE Tmax T4 series, the T4V250 is engineered for demanding industrial and commercial power distribution applications where very high short-circuit interruption capability is required. Its TMA release combines adjustable thermal overload protection with adjustable instantaneous magnetic protection, helping safeguard cables, equipment and distribution circuits against damaging overcurrents.
The TMA release is rated at 200 A, with instantaneous magnetic protection adjustable from 1,000–2,000 A. With its four-pole construction, fixed mounting arrangement and front terminals, the 1SDA054259R1 is particularly suitable for switchboards and distribution systems requiring comprehensive multipole circuit protection.

Reliable Circuit Protection for Power Distribution
Moulded case circuit breakers such as the ABB SACE Tmax T4V protect electrical distribution circuits against damaging overcurrents while also providing a convenient means of circuit isolation. The T4V platform combines compact construction with high short-circuit interruption performance, making it suitable for demanding industrial and commercial low-voltage distribution applications.
The TMA thermomagnetic trip unit provides complementary overload and short-circuit protection. Its thermal element responds to sustained overload currents that could overheat cables and connected equipment, while its adjustable magnetic element provides rapid tripping during severe short-circuit conditions. The four-pole configuration makes this breaker suitable for distribution arrangements where switching and protection across four poles are required.
