Why Choose the ABB 1SDA054148R1 T4L 320 Circuit Breaker?
The ABB 1SDA054148R1 is a SACE Tmax T4L 320 four-pole moulded case circuit breaker designed for demanding low-voltage power distribution applications. It combines a 320 A rated current with ABB's PR222DS/P-LSIG electronic trip unit, providing electronic protection against overload, short-circuit and ground-fault conditions.
The PR222DS/P-LSIG solid-state release provides long-time, short-time, instantaneous and ground-fault protection functions. This LSIG protection architecture gives the breaker comprehensive overcurrent and earth-fault protection capabilities for suitably engineered industrial, commercial and infrastructure distribution systems.
The 1SDA054148R1 features a fixed four-pole construction with front terminals. Its T4L 320 configuration combines a compact ABB Tmax frame with a 320 A electronic release, making it suitable for high-current feeders and distribution circuits where four-pole switching, electronic LSIG protection and dependable short-circuit interruption are required.

Four-Pole LSIG Protection for High-Current Distribution
The PR222DS/P-LSIG electronic trip unit provides four principal protection functions. Long-time protection responds to sustained overload conditions, short-time protection addresses elevated fault currents while supporting system coordination, instantaneous protection enables rapid interruption of severe short circuits, and ground-fault protection adds dedicated protection against earth-fault conditions.
In the ABB 1SDA054148R1, these electronic protection functions are combined with a 320 A rated current and four-pole T4L construction. This combination makes the breaker particularly suitable for high-current feeder and distribution applications requiring comprehensive LSIG protection, four-pole switching and the integration flexibility of a fixed front-terminal MCCB.
Typical Applications
- Four-pole low-voltage distribution systems.
- Three-phase and neutral power distribution.
