Why Choose the ABB 1SDA060789R1 E3H-A 800 PR121/P-LI Moving Part?
The ABB 1SDA060789R1, identified as E3H-A 800 PR121/P-LI In=800A 3p W MP, is a three-pole moving part for a withdrawable SACE Emax E3H-A air circuit breaker. Designed for demanding low-voltage power-distribution applications, it combines an 800 A rated current with ABB’s PR121/P electronic overcurrent release and the higher-performance E3H-A breaker platform.
The fitted PR121/P-LI electronic trip unit uses an R800 rating plug and provides long-time overload protection together with instantaneous short-circuit protection. The configuration has an instantaneous protection value of 12,000 A, providing rapid response to severe fault currents while retaining electronic overload protection for normal distribution duties.
As a withdrawable moving part, the 1SDA060789R1 is designed to interface with the appropriate SACE Emax E3 fixed part installed in the switchboard. This architecture allows the breaker moving section to be withdrawn for isolation, inspection or maintenance while the fixed switchboard connections remain installed.
Key Advantages
- Genuine ABB SACE Emax E3H-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 fixed section installed in the switchboard. The 1SDA060789R1 can therefore be withdrawn from its compatible fixed part when isolation, inspection, maintenance or replacement is required without dismantling the principal switchboard power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 E3H-A platform, R800 rating plug, auxiliary contacts and withdrawable construction, this configuration provides a service-friendly protection solution for demanding low-voltage distribution systems.
Typical Applications
- Industrial low-voltage main distribution switchboards.
- ABB SACE Emax E3H-A withdrawable circuit-breaker installations.
- Main incoming circuit protection.
- Industrial feeder protection.
- Manufacturing and process-industry switchgear.
- Commercial and infrastructure power-distribution systems.
- Systems requiring 800 A LI electronic overcurrent protection.
