Why Choose the ABB E2S800 PR122/P-LSIG 800A Air Circuit Breaker?
The ABB E2S800 PR122/P-LSIG is a high-performance 800 A air circuit breaker (ACB) designed for reliable protection and switching of low-voltage electrical distribution systems. As part of the proven ABB SACE Emax E2 series, this three-pole fixed circuit breaker combines high interruption performance with the advanced PR122/P electronic trip unit for precise protection of industrial and commercial power networks.
Equipped with LSIG protection, the PR122/P trip unit provides long-time overload, short-time short-circuit, instantaneous short-circuit and ground-fault protection. This comprehensive protection package enables the breaker to respond accurately to multiple fault conditions while supporting selective coordination and dependable operation within complex low-voltage distribution systems.
With a rated current of 800 A and an E2S breaking-capacity class of 85 kA at 415 V AC, the E2S800 is suitable for demanding power-distribution applications. This version features a three-pole fixed construction with horizontal rear terminals and an 800 A PR122/P-LSIG overcurrent release, providing a robust solution for installation in switchboards and industrial power-control assemblies.

Reliable Protection for Low-Voltage Power Distribution
Air circuit breakers such as the ABB E2S800 protect electrical distribution equipment against overloads, short circuits and ground faults while also providing controlled switching and isolation. Their high breaking capacity makes them particularly suitable for main distribution boards and installations where substantial prospective fault currents may occur.
The PR122/P electronic trip unit enhances protection flexibility by providing independently configurable long-time, short-time, instantaneous and ground-fault functions. This LSIG protection architecture supports coordination with upstream and downstream protective devices, helping improve selectivity, continuity of service and overall electrical-system protection.
Typical Applications
- Main low-voltage distribution switchboards.
- Industrial power distribution systems.
- Manufacturing and process plants.
- Commercial and infrastructure electrical installations.
- Power distribution centres and switchgear assemblies.
- Transformer secondary and feeder protection.
- Generator and utility distribution systems.
- High-current machinery and plant distribution circuits.
