The ABB 1SDA054428R1 is a high-performance SACE Tmax T5V moulded case circuit breaker (MCCB) designed for dependable protection and switching in demanding industrial and commercial low-voltage power distribution systems. Part of the proven ABB SACE Tmax T5 series, this three-pole circuit breaker combines a 630 A rated current with a PR221DS-LS/I solid-state electronic trip unit.
The PR221DS-LS/I electronic release provides long-time overload protection together with short-circuit protection, offering greater precision and flexibility than conventional thermomagnetic protection. This makes the breaker well suited to higher-current feeders where accurate protection coordination is important for cables, switchgear and downstream electrical equipment.
With a rated uninterrupted current of 630 A, three-pole construction, fixed installation and front terminals, the T5V 630 PR221DS-LS/I is designed for integration into industrial switchboards and distribution assemblies. The high-performance T5V version provides an ultimate short-circuit breaking capacity of 200 kA at 415 V AC, making it particularly suitable for installations with exceptionally high prospective fault currents.
Electronic moulded case circuit breakers such as the ABB SACE Tmax T5V provide accurate protection for high-current electrical distribution circuits. The PR221DS-LS/I release combines long-time overload protection with short-circuit protection, helping protect cables, feeders and connected equipment while supporting effective coordination within the wider electrical distribution system.
The 630 A rating makes the 1SDA054428R1 suitable for substantial three-phase feeders and high-current distribution circuits, while the T5V platform's 200 kA ultimate breaking capacity at 415 V AC provides exceptionally high fault-current interruption capability. This combination makes the breaker particularly suitable for industrial switchboards and installations where high prospective short-circuit currents demand robust protection.
