The ABB T5L400 PR221DS-LS/I In400 3p FFC, order code 1SDA054535R1, is a high-voltage three-pole moulded case circuit breaker (MCCB) from the ABB SACE Tmax T range, designed for dependable protection of industrial AC electrical distribution systems. Built on the T5L 400 frame, it combines fixed installation with a PR221DS-LS/I solid-state electronic trip unit rated at 400 A.
Designed for specialised high-voltage applications, this circuit breaker has a rated operational voltage of 1000 V AC, a rated uninterrupted current of 400 A and a rated insulation voltage of 1150 V. Its L breaking-performance level provides an ultimate short-circuit breaking capacity of 12 kA at 1000 V AC and a service short-circuit breaking capacity of 10 kA at 1000 V AC.
The PR221DS-LS/I release provides electronic overload and short-circuit protection, with the overload setting adjustable from 160–400 A. The breaker is supplied in a fixed three-pole configuration with front terminals for copper cables, making it suitable for industrial switchboards and specialised 1000 V AC distribution installations.
The ABB PR221DS-LS/I electronic trip unit provides protection against overload and short-circuit conditions while allowing the overload threshold to be adjusted for the requirements of the protected circuit. Electronic protection provides accurate and repeatable operation for industrial distribution systems where dependable fault protection is essential.
The T5L version of the Tmax T platform is engineered for demanding high-voltage AC applications. Its 400 A current rating, fixed three-pole construction and front copper-cable terminals provide a practical solution for specialised 1000 V AC industrial distribution systems.
