1SDA054385R1 ABB T5V 400 PR222DS/P-LSI In=400 3P F F Moulded Case Circuit Breaker 400 A

Why Choose the ABB T5V 400 PR222DS/P-LSI In=400 3P F F Circuit Breaker?

The ABB 1SDA054385R1 is a high-performance SACE Tmax T5V moulded case circuit breaker (MCCB) designed for advanced 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 400 A rating with a PR222DS/P-LSI solid-state electronic trip unit.

The PR222DS/P-LSI electronic release provides LSI protection functions, combining long-time overload, short-time short-circuit and instantaneous short-circuit protection. The thermal protection is adjustable from 0.4–1 × In, while the magnetic protection can be adjusted from 1.5–12 × In, providing considerable flexibility when coordinating protection with cables, feeders and downstream equipment.

With a rated current of 400 A, three-pole construction, fixed installation and front terminals, the T5V 400 PR222DS/P-LSI is designed for straightforward integration into low-voltage switchboards and distribution assemblies. Its V performance level provides an exceptional ultimate short-circuit breaking capacity of 200 kA at 380–415 V AC, making it particularly suitable for installations with very high prospective fault currents.

Advanced LSI Protection for Power Distribution

Electronic moulded case circuit breakers such as the ABB SACE Tmax T5V provide flexible protection for higher-current electrical distribution circuits. The PR222DS/P-LSI release incorporates separate long-time, short-time and instantaneous protection functions, allowing the protection characteristics to be coordinated more precisely with cables, feeders and downstream protective devices than with conventional fixed protection.

The 400 A rating makes the 1SDA054385R1 suitable for substantial three-phase feeders, while the T5V platform's 200 kA ultimate breaking capacity at 380–415 V AC provides exceptionally high short-circuit interruption capability. This combination makes the breaker particularly suitable for industrial switchboards and distribution systems where both high fault levels and selective protection coordination are important.

Typical Applications

• Industrial low-voltage power distribution systems.
• Main and sub-distribution switchboards.
• Three-phase feeder circuit protection.
• Manufacturing and process plant electrical systems.
• Commercial building power distribution.
• Infrastructure and utility electrical installations.
• Industrial machinery and production facilities.
• Installations with exceptionally high prospective short-circuit currents.
