Why Choose the ABB 1SDA060803R1 E3H-A 800 SACE Emax Air Circuit Breaker?
The ABB 1SDA060803R1, designated E3H-A 800 PR122/P-LSI In=800A 3p F, is a genuine SACE Emax E3H-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 fixed construction and ABB's PR122/P electronic overcurrent release.
The integrated PR122/P-LSI overcurrent release provides long-time (L), short-time (S) and instantaneous (I) protection functions. The breaker uses an R800 release with an instantaneous setting reference of 12000 A, providing electronic protection against overload and short-circuit conditions in appropriately engineered distribution systems.
This E3H-A model is a fixed version with horizontal rear terminals and a UL configuration. It is also fitted with 4 auxiliary contacts and open/closed position indication, supporting breaker status monitoring and integration into compatible switchboard control systems.

Comprehensive LSI Protection for Power Distribution
The ABB PR122/P electronic overcurrent release provides multiple protection functions within one integrated unit. Long-time protection addresses sustained overload conditions, while short-time and instantaneous functions provide protection against short-circuit currents, helping protect conductors and downstream equipment within a properly coordinated electrical distribution system.
The ABB 1SDA060803R1 combines these electronic protection capabilities with an 800 A, three-pole fixed E3H-A breaker and horizontal rear terminals. Its fixed construction is suited to permanent switchboard installations where robust circuit protection, rear-connected power connections and auxiliary breaker status signalling are required.
Typical Applications
- Industrial low-voltage power distribution systems.
- Main and sub-main distribution switchboards.
- Three-phase feeder and circuit protection.
- Manufacturing and process plant electrical systems.
- Commercial and infrastructure power distribution.
- ABB SACE Emax switchgear refurbishment and lifecycle replacement projects.
