Why Choose the ABB 1SDA060757R1 E3S-A 800 PR121/P-LI Withdrawable Air Circuit Breaker?
The ABB 1SDA060757R1, identified as E3S-A 800 PR121/P-LI In=800A 3p W MP, is a three-pole moving part for a withdrawable SACE Emax E3S-A air circuit breaker. Designed for demanding low-voltage power-distribution systems, it combines an 800 A rated current with ABB’s PR121/P electronic overcurrent release.
The fitted PR121/P-LI electronic trip unit provides long-time overload and instantaneous short-circuit protection. This LI protection combination is designed to protect electrical distribution circuits against sustained overcurrents and severe short-circuit conditions while providing the flexibility and accuracy of an electronic trip unit.
As a withdrawable moving part, the 1SDA060757R1 is designed to interface with a compatible SACE Emax E3 fixed part installed in the switchboard. The withdrawable architecture enables the breaker moving section to be isolated and removed for inspection, servicing or replacement while the fixed switchboard connections remain installed.
Key Advantages
- Genuine ABB SACE Emax E3S-A moving part for withdrawable circuit-breaker installations.
- 800 A rated current for substantial low-voltage distribution loads.

Reliable LI Protection in Withdrawable Emax Switchgear
ABB’s withdrawable SACE Emax architecture separates the removable circuit-breaker moving part from the permanently installed fixed part. The 1SDA060757R1 can therefore be withdrawn from its compatible fixed section when isolation, inspection, maintenance or replacement is required without dismantling the principal switchboard power connections.
The PR121/P-LI electronic release provides long-time protection against sustained overload conditions and instantaneous protection against severe short circuits. Combined with the 800 A E3S-A platform and withdrawable construction, this configuration provides a practical protection solution for switchboards where serviceability and dependable circuit protection are important.
Typical Applications
