Why Choose the ABB 1SDA060777R1 E3S-A 800 SACE Emax Air Circuit Breaker?
The ABB 1SDA060777R1, designated E3S-A 800 PR122/P-LSIG In=800A 3p W, is a genuine SACE Emax E3S-A air circuit breaker engineered for dependable protection and switching in demanding low-voltage power distribution systems. It combines an 800 A rated current with three-pole construction, withdrawable execution and ABB's PR122/P electronic overcurrent release.
The integrated PR122/P-LSIG trip unit provides long-time (L), short-time (S), instantaneous (I) and ground-fault (G) protection functions. This combination enables comprehensive protection against sustained overloads, short-circuit currents and ground-fault conditions within appropriately engineered electrical distribution systems.
The W designation identifies the breaker as a withdrawable version, allowing the moving part to be withdrawn from a compatible SACE Emax fixed part for inspection, maintenance or replacement. This architecture is particularly valuable in switchgear where serviceability and reduced maintenance disruption are important requirements.
Key Advantages
- Genuine ABB SACE Emax E3S-A air circuit breaker.
- 800 A rated current for low-voltage power distribution.
- PR122/P-LSIG electronic trip unit for comprehensive circuit protection.
- LSIG protection functions cover long-time, short-time, instantaneous and ground-fault protection.
- 3-pole configuration for three-phase distribution systems.
- Withdrawable execution supports efficient inspection, servicing and replacement.

Withdrawable LSIG Protection for Power Distribution
The ABB PR122/P electronic trip unit provides multiple protection functions within one integrated release. Long-time protection addresses sustained overload conditions, short-time and instantaneous functions provide protection against short-circuit currents, and ground-fault protection adds dedicated protection for earth-fault conditions within the configured electrical distribution system.
The ABB 1SDA060777R1 combines these electronic protection capabilities with an 800 A, three-pole E3S-A breaker in withdrawable execution. The withdrawable architecture allows the breaker moving part to be disconnected and removed from its compatible fixed part, supporting maintainable switchgear installations where inspection and equipment replacement need to be carried out efficiently.
Typical Applications
- Industrial low-voltage power distribution systems.
- Main and sub-main distribution switchboards.
- Withdrawable three-phase feeder protection.
- Manufacturing and process plant electrical systems.
- Commercial and infrastructure power distribution.
- ABB SACE Emax switchgear refurbishment and lifecycle replacement projects.
