Why Choose the ABB 1SDA060771R1 E3S-A 800 Air Circuit Breaker?
The ABB 1SDA060771R1 is a SACE Emax E3S-A 800 air circuit breaker designed for dependable protection and switching in demanding low-voltage power distribution systems. This three-pole fixed breaker combines an 800 A rated current with ABB's PR122/P-LSI electronic overcurrent release, providing long-time, short-time and instantaneous protection functions.
Configured as a three-pole fixed breaker, the 1SDA060771R1 features horizontal rear (HR) terminals for integration with compatible switchboard busbars and conductors. Its E3 frame and S performance designation provide a robust platform for industrial, commercial and infrastructure distribution systems requiring reliable circuit protection.
The fitted PR122/P-LSI R800 electronic trip unit provides configurable LSI protection for coordination with other protective devices in the electrical system. This specific ABB configuration is identified with a 12,000 A instantaneous reference and is supplied as a fixed, three-pole, horizontal-rear-terminal UL configuration.

PR122/P-LSI Electronic Circuit Protection
The ABB PR122/P-LSI electronic trip unit combines three important protection functions for low-voltage distribution. The L function provides long-time protection against sustained overloads, the S function provides short-time protection that supports selective coordination, and the I function provides rapid intervention during severe short-circuit conditions.
This combination makes the 1SDA060771R1 suitable for distribution systems where coordinated protection is important. Its 800 A rating, fixed construction and horizontal rear connections provide a practical configuration for main distribution, feeder and other appropriately engineered low-voltage switchboard circuits.
Typical Applications
- Main low-voltage power distribution switchboards.
- Industrial electrical distribution systems.
- Commercial and infrastructure main distribution boards.
- Manufacturing and process plant switchgear.
- Transformer secondary protection and distribution.
- Generator distribution systems where the breaker characteristics match the system design.
- Main incomer and feeder circuit-breaker applications.
- Fixed switchgear requiring coordinated electronic LSI protection.
