Why Choose the ABB T5L400 PR222DS/P-LSI 320 A 1SDA054368R1 Circuit Breaker?
The ABB 1SDA054368R1 is a high-performance SACE Tmax T5L 400 moulded case circuit breaker (MCCB) designed for reliable protection and isolation of demanding low-voltage electrical distribution systems. Configured as a fixed three-pole breaker with front terminals, it combines a 320 A rated current with ABB's PR222DS/P-LSI electronic trip unit.
Part of the proven ABB SACE Tmax T5 series, the T5L400 provides electronic LSI protection, covering long-time overload, short-time short-circuit and instantaneous short-circuit faults. The electronic release offers considerably greater protection flexibility than a conventional fixed thermomagnetic trip unit, making this breaker well suited to industrial switchboards and coordinated distribution networks.
The PR222DS/P-LSI release provides a 128–320 A overload adjustment range, a 192–3,200 A short-time delayed short-circuit adjustment range and a 480–3,840 A instantaneous short-circuit adjustment range. Combined with the T5L's 120 kA breaking capacity at 400 V AC, this gives the 1SDA054368R1 strong protection capability for installations with substantial prospective fault currents.

Reliable Electronic Protection for Power Distribution
The ABB SACE Tmax T5L platform is designed for demanding low-voltage power distribution where high breaking performance and flexible protection settings are important. With a 400 A frame size and a 320 A electronic release, the 1SDA054368R1 provides substantial circuit capacity while allowing protection settings to be coordinated with cables, downstream equipment and other protective devices.
Its PR222DS/P-LSI electronic trip unit independently addresses long-time overload, short-time short-circuit and instantaneous fault conditions. This combination allows more selective protection than basic thermomagnetic switching, helping improve coordination and continuity within industrial and commercial electrical distribution networks.
Typical Applications
- Industrial low-voltage power distribution systems.
- Main and sub-distribution switchboards.
- Three-phase electrical distribution panels.
- Manufacturing and process installations.
- Commercial and infrastructure power distribution.
- Machinery and plant electrical distribution systems.
