Why Choose the ABB 1SDA054143R1 T4L 320 PR222DS/P-LSI Circuit Breaker?
The ABB 1SDA054143R1 is a SACE Tmax T4L 320 moulded case circuit breaker designed for dependable protection and switching in low-voltage electrical distribution systems. ABB specifies this configuration as T4L 320 PR222DS/P-LSI IN=320, combining the T4L platform with a rated current of 320 A.
At the heart of the breaker is the ABB PR222DS/P-LSI electronic trip unit, providing long-time, short-time and instantaneous overcurrent protection. These LSI functions allow the breaker to protect against sustained overloads as well as short-circuit faults, supporting effective protection coordination within suitably engineered electrical systems.
As part of the established ABB SACE Tmax family, the 1SDA054143R1 provides electronic protection in a compact moulded case format. Its 320 A rating makes it suitable for feeder, distribution and industrial applications requiring the T4L performance level and PR222DS/P protection functionality.

Electronic LSI Protection for Power Distribution
The PR222DS/P-LSI trip unit combines three important overcurrent protection functions. Long-time protection addresses sustained overload conditions, short-time protection responds to short-circuit currents with characteristics that can support system coordination, and instantaneous protection provides rapid tripping for severe short-circuit faults.
This combination makes the ABB 1SDA054143R1 suitable for electrical distribution systems requiring more flexible protection than a simple instantaneous-only trip unit. Together with the 320 A T4L platform, it provides a practical solution for protecting feeders and distribution circuits in industrial, commercial and infrastructure installations.
Typical Applications
- Industrial low-voltage power distribution.
- Main and sub-distribution switchboards.
- Feeder circuit protection.
- Commercial building electrical distribution.
- Industrial machinery and electrical panels.
- Power distribution systems requiring LSI protection.
- OEM switchgear and distribution assemblies.
