The ABB 1SDA054229R1, designated T4L 250 TMA 100-1000 3p F F, is a high-performance moulded case circuit breaker (MCCB) designed for dependable protection of low-voltage power distribution circuits. As part of the proven ABB SACE Tmax T4 series, it combines compact construction with thermal-magnetic protection and high short-circuit interruption performance for industrial and commercial electrical installations.
This circuit breaker is equipped with an ABB TMA thermal-magnetic trip unit rated at 100 A. The thermal element provides overload protection, while the magnetic element provides rapid protection against high short-circuit currents, delivering a straightforward and dependable protection solution without requiring an electronic trip unit.
The T4L 250 is supplied as a fixed three-pole circuit breaker with front terminals. The designation TMA 100-1000 identifies the 100 A thermal-magnetic release with magnetic protection up to 1000 A, while the L performance level is intended for installations requiring high short-circuit breaking capability.
Thermal-magnetic moulded case circuit breakers such as the ABB T4L 250 combine two complementary protection principles. The thermal element responds to sustained overload currents that can overheat conductors and equipment, while the magnetic element operates rapidly when a severe short circuit produces a high fault current.
The T4L platform combines this straightforward protection technology with the robust construction and high interruption performance required in modern low-voltage distribution systems. Its fixed three-pole arrangement and front terminals make the 1SDA054229R1 suitable for integration into industrial switchboards, distribution panels and machinery power systems.
