Why Choose the ABB E3H800 PR122/P-LSI 800A 3-Pole Air Circuit Breaker?
The ABB E3H800 PR122/P-LSI, order code 1SDA056340R1, is a high-performance SACE Emax air circuit breaker (ACB) designed for switching and protection in demanding low-voltage electrical distribution systems. As part of the ABB SACE Emax E3 series, this three-pole fixed circuit breaker combines an 800 A rated uninterrupted current with the PR122/P-LSI electronic overcurrent release.
The PR122/P-LSI trip unit provides long-time overload, short-time short-circuit and instantaneous short-circuit protection. This LSI configuration supports selective coordination and dependable protection against sustained overloads and short-circuit faults, making the breaker suitable for industrial, commercial and infrastructure power distribution applications.
With an 800 A rated current, three-pole configuration, fixed construction and rear horizontal terminals, the E3H800 is designed for permanent integration into low-voltage switchboards. Its high-performance E3H configuration provides a rated ultimate short-circuit breaking capacity of 100 kA at 400–415 V AC, together with a rated service short-circuit breaking capacity of 85 kA at 400–415 V AC.

High-Performance Circuit Protection for Low-Voltage Power Distribution
Air circuit breakers such as the ABB SACE Emax E3H800 provide switching, isolation and overcurrent protection for important low-voltage distribution circuits. The electronic trip unit monitors current conditions and initiates circuit-breaker operation when configured protection thresholds are exceeded, helping protect cables, switchgear and connected electrical equipment against damaging overloads and short circuits.
The PR122/P-LSI release provides three complementary levels of overcurrent protection. Long-time protection responds to sustained overloads, short-time protection enables controlled fault clearing and improved selectivity, and instantaneous protection provides rapid interruption of severe short-circuit currents. Combined with the E3H breaker’s high short-circuit performance, this makes the 1SDA056340R1 well suited to distribution systems with high prospective fault levels.
Typical Applications
- Main low-voltage electrical distribution switchboards.
- Industrial power distribution systems.
- Transformer and generator protection.
- Commercial and infrastructure electrical installations.
- Manufacturing and process facilities.
- High-current incomer and feeder protection.
