Why Choose the ABB 1SDA054367R1 T5L 400 Moulded Case Circuit Breaker?
The ABB 1SDA054367R1, designated T5L 400 PR221DS-I In=400 3p F F, is a high-performance moulded case circuit breaker (MCCB) designed for dependable protection of demanding low-voltage power distribution systems. Part of the ABB SACE Tmax T5 series, it combines a 400 A current rating with a PR221DS-I solid-state electronic release and the high short-circuit performance of the T5L platform.
The PR221DS-I electronic trip unit provides long-time overload and instantaneous short-circuit protection. Its overload protection can be set from 160–400 A, while the instantaneous short-circuit protection range extends from 400–4000 A, providing flexibility when coordinating protection within industrial and commercial electrical distribution systems.
The T5L 400 is supplied as a fixed three-pole circuit breaker with front terminals. With a rated operational voltage of up to 690 V AC, a rated insulation voltage of 1000 V and the L short-circuit performance level, the 1SDA054367R1 is engineered for robust integration into low-voltage switchboards and distribution assemblies.
