Why Choose the ABB E3N2500 PR122/P-LI 2500A 4-Pole Air Circuit Breaker?
The ABB E3N2500 PR122/P-LI, order code 1SDA056123R1, is a high-performance SACE Emax air circuit breaker (ACB) designed for switching and protection in high-current low-voltage electrical distribution systems. As part of the ABB SACE Emax E3 series, this four-pole fixed circuit breaker combines a 2500 A rated current with the advanced PR122/P-LI electronic overcurrent release.
The PR122/P-LI trip unit provides long-time overload and instantaneous short-circuit protection, helping protect electrical distribution equipment against damaging overcurrent and fault conditions. The PR122/P platform provides electronic protection and monitoring functionality for demanding industrial and commercial power distribution applications.
With a 2500 A rated current, four-pole configuration and fixed construction, the E3N2500 is well suited to main switchboards, distribution systems and other high-current installations. This configuration features rear horizontal terminals and is fitted with four auxiliary contacts together with circuit-breaker open/closed position indication.

Reliable Circuit Protection for High-Current Power Distribution
Air circuit breakers such as the ABB SACE Emax E3N2500 provide switching, isolation and overcurrent protection for high-current 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.
The PR122/P-LI release provides two fundamental overcurrent protection functions. Long-time protection responds to sustained overload conditions, while instantaneous protection provides rapid operation in response to severe short-circuit currents, making this configuration suitable for electrical networks where LI protection is required.
Typical Applications
- Main low-voltage electrical distribution switchboards.
- Industrial power distribution systems.
- Commercial and infrastructure electrical installations.
- Manufacturing and process facilities.
- High-current incomer and feeder protection.
- Transformer and generator distribution systems.
