Why Choose the ABB 1SDA054089R1 T4L 250 Circuit Breaker?
The ABB 1SDA054089R1 is a SACE Tmax T4L 250 four-pole moulded-case circuit breaker designed for protection and switching in AC low-voltage power distribution systems. This fixed breaker features front terminals and a 250 A PR222DS/P-LSI solid-state electronic trip unit, combining the full current capability of the T4 250 frame with configurable electronic protection.
The PR222DS/P-LSI release provides long-time (L), short-time (S) and instantaneous (I) overcurrent protection. These protection functions allow the breaker to respond appropriately to sustained overloads, delayed short-circuit conditions and severe instantaneous faults, supporting selective and coordinated protection within industrial and commercial distribution systems.
ABB order code 1SDA054089R1 is configured as a four-pole fixed circuit breaker with front terminals. Its T4L performance level is intended for installations requiring high short-circuit interruption capability, while the four-pole construction supports three-phase distribution systems where the neutral conductor also needs to be switched.
Key Advantages
- Genuine ABB SACE Tmax T4L 250 moulded-case circuit breaker.

Electronic LSI Protection with the PR222DS/P Trip Unit
The PR222DS/P-LSI electronic trip unit provides three complementary overcurrent protection functions. Long-time protection responds to sustained overloads, short-time protection provides a controlled response to higher short-circuit currents, and instantaneous protection operates rapidly when severe fault currents are detected.
This combination provides greater protection flexibility than a basic fixed-response breaker and can assist with coordination between upstream and downstream protective devices. Combined with the T4L 250 platform and 250 A rating, the ABB 1SDA054089R1 is well suited to demanding feeder and distribution applications requiring electronic LSI protection.
Typical Applications
- Industrial low-voltage power distribution.
- Main and sub-distribution switchboards.
- Four-pole three-phase and neutral circuits.
- 250 A feeder circuit protection.
- Commercial building electrical distribution.
- Manufacturing and process installations.
- Infrastructure and utility distribution panels.
- Systems requiring electronic LSI overcurrent protection.
- Installations requiring a high-performance fixed MCCB.
