The ABB 1SDA054241R1, designated T4L 250 TMA 200-2000 4p F F, is a high-performance moulded case circuit breaker (MCCB) designed for reliable protection of low-voltage power distribution systems. Part of the proven ABB SACE Tmax T4 series, it combines a compact 250 A frame with thermal-magnetic protection and high short-circuit interruption performance for demanding industrial and commercial installations.
This circuit breaker incorporates an ABB TMA thermal-magnetic release with a rated current of 200 A. Its thermal element provides overload protection, while the adjustable magnetic element provides rapid short-circuit protection over an I3 range of 1000–2000 A, allowing the protection characteristics to be matched more effectively to the application.
The T4L 250 is supplied as a fixed four-pole circuit breaker with front terminals. This configuration enables simultaneous switching and protection across four conductors in suitable three-phase distribution systems, while the L performance class provides the high fault-current interruption capability associated with the Tmax T4L platform.
Thermal-magnetic moulded case circuit breakers such as the ABB T4L 250 combine complementary overload and short-circuit protection technologies. The thermal element responds to sustained overcurrents that could overheat conductors and equipment, while the magnetic element operates rapidly during high-current short-circuit faults.
For the 1SDA054241R1, the magnetic protection threshold is adjustable across 1000–2000 A, providing greater flexibility than a single fixed instantaneous setting. Combined with its four-pole construction, fixed mounting and front terminals, this makes the breaker a practical protection solution for industrial switchboards, distribution panels and commercial low-voltage power systems.
