The ABB 1SDA054387R1, designated T5V 400 PR222DS/P-LSIG In=400 3p F F, is a high-performance moulded case circuit breaker (MCCB) engineered for demanding low-voltage power distribution systems. Part of the ABB SACE Tmax T5 series, it combines a 400 A current rating with a PR222DS/P-LSIG solid-state electronic release and the exceptionally high short-circuit interruption capability of the T5V platform.
The PR222DS/P-LSIG electronic trip unit provides long-time overload, short-time short-circuit, instantaneous short-circuit and ground-fault protection. Its overload setting covers 160–400 A, short-time protection is adjustable from 240–4000 A, and instantaneous protection is adjustable from 600–4800 A, providing extensive flexibility for protection coordination.
The T5V 400 is supplied as a fixed three-pole circuit breaker with front terminals. With a rated operational voltage of 690 V AC and an ultimate short-circuit breaking capacity of 200 kA at 400 V AC, the 1SDA054387R1 is particularly suited to industrial and commercial distribution systems where exceptionally high prospective fault currents must be safely interrupted.
The ABB PR222DS/P-LSIG electronic release provides comprehensive protection for demanding low-voltage distribution networks. Long-time protection responds to sustained overload conditions, short-time protection supports selective coordination during short circuits, instantaneous protection provides rapid interruption of severe faults, and integrated ground-fault protection extends coverage to earth-fault conditions.
With overload protection adjustable from 160–400 A, short-time protection from 240–4000 A and instantaneous protection from 600–4800 A, the 1SDA054387R1 offers considerable flexibility for system coordination. Combined with the T5V platform's 200 kA breaking capacity at 400 V AC, it provides a robust solution for switchboards where high fault levels and comprehensive electronic protection are required.
