Why Choose the ABB 1SDA054386R1 T5V 400 Moulded Case Circuit Breaker?
The ABB 1SDA054386R1, designated T5V 400 PR222DS/P-LSIG In=320 3p F F, is a high-performance moulded case circuit breaker (MCCB) designed for demanding low-voltage power distribution systems. Part of the ABB SACE Tmax T5 series, it combines a 400 A frame with a 320 A PR222DS/P-LSIG electronic trip unit and the very high short-circuit interruption capability of the T5V platform.
The PR222DS/P-LSIG solid-state electronic release provides long-time overload, short-time short-circuit, instantaneous short-circuit and ground-fault protection. Its short-time delayed short-circuit setting covers 192–3200 A, while the instantaneous short-circuit setting covers 480–3840 A, providing flexible protection coordination for complex industrial distribution systems.
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 415 V AC, the 1SDA054386R1 is engineered for installations where exceptionally high prospective fault currents require dependable interruption.

Reliable Electronic Protection for Industrial Power Distribution
The ABB PR222DS/P-LSIG electronic release provides a comprehensive combination of protection functions for demanding low-voltage networks. Long-time protection responds to sustained overload conditions, short-time protection supports selective coordination during short circuits, instantaneous protection rapidly interrupts severe faults, and ground-fault protection extends coverage to earth-fault conditions.
The 1SDA054386R1 combines these LSIG protection functions with adjustable short-time protection from 192–3200 A, adjustable instantaneous protection from 480–3840 A and the T5V platform's exceptional 200 kA breaking capacity at 415 V AC. This makes it a strong choice for critical industrial switchboards and distribution systems with high prospective fault currents.
Typical Applications
- Industrial low-voltage power distribution systems.
- Main and feeder protection in high-fault-level switchboards.
- Three-phase electrical distribution circuits.
- Manufacturing and process plant power systems.
- Commercial and infrastructure electrical distribution.
- Installations requiring LSIG electronic protection and very high short-circuit interruption capability.
