Why Choose the ABB E3S2000PR122/P-LSI 2000A Air Circuit Breaker?
The ABB E3S2000PR122/P-LSI is a high-performance 2000 A four-pole air circuit breaker moving part designed for reliable switching and overcurrent protection in demanding low-voltage power distribution systems. As part of the established ABB SACE Emax New Emax series, this E3S configuration combines a robust high-current breaker platform with the advanced 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. These LSI protection functions help safeguard cables, busbars, switchboards and connected electrical equipment against sustained overloads and short-circuit faults while supporting selective protection and coordination within industrial and commercial electrical distribution networks.
With a rated current of 2000 A, a four-pole withdrawable moving-part configuration and an E3S performance level designed for demanding fault conditions, ABB order code 1SDA056268R1 is intended for compatible SACE Emax withdrawable switchgear. The moving part incorporates a PR122/P-LSI R2000 release, four auxiliary contacts and circuit-breaker open/closed position indication for monitoring and control integration.

Reliable Protection for High-Current Power Distribution
Air circuit breakers such as the ABB E3S2000 provide switching and overcurrent protection for high-current low-voltage distribution circuits. The electronic trip release monitors circuit conditions and initiates breaker operation when configured protection thresholds are exceeded, helping protect cables, busbars, switchboards and connected electrical equipment against damaging overload and short-circuit currents.
The PR122/P-LSI release combines long-time, short-time and instantaneous protection functions in an electronic trip system. Together with the 2000 A four-pole E3S configuration, high short-circuit performance and service-friendly withdrawable construction, this moving part is well suited to critical main distribution and high-current feeder applications where neutral switching is required.
Typical Applications
- Low-voltage main distribution switchboards.
- Industrial power distribution systems.
- Four-wire three-phase distribution networks.
- Manufacturing and process facilities.
- Commercial and infrastructure electrical installations.
- Incoming mains and high-current feeder protection.
- Transformer secondary distribution systems.
- Withdrawable ABB SACE Emax switchgear assemblies.
