The ABB 1SDA054409R1 is a dependable SACE Tmax T5S moulded case circuit breaker (MCCB) designed for reliable protection of industrial power distribution systems, switchboards, machinery and commercial electrical installations. As part of the proven ABB Tmax T series, it offers robust circuit protection in a compact four-pole fixed design.
This MCCB features a 630 A rated current, four-pole configuration and a PR221DS-I electronic trip unit, providing accurate short-circuit protection for low voltage AC networks. Its fixed mounting format with front terminals allows straightforward installation into distribution panels, control cabinets and switchgear assemblies.
With a rated operational voltage of up to 690 V AC and a short-circuit performance level of S, the ABB 1SDA054409R1 is suitable for demanding three-phase and neutral electrical systems where dependable protection, safe operation and continuity of service are essential.
Moulded case circuit breakers such as the ABB Tmax T5S help protect electrical installations by interrupting fault currents and preventing damage caused by overloads, short circuits and abnormal electrical conditions. Electronic trip technology supports accurate protection and improved reliability in low voltage distribution systems.
The four-pole configuration makes this breaker suitable for systems where the neutral conductor also requires switching, making it a practical choice for industrial switchboards, commercial distribution panels and critical infrastructure applications.
