Why Choose the ABB E3V2500 PR122/P-LSI Air Circuit Breaker?
The ABB E3V2500 PR122/P-LSI, order code 1SDA056660R1, is a high-performance SACE Emax air circuit breaker (ACB) designed for protection and switching in high-current low-voltage power-distribution systems. Part of the ABB SACE Emax E3 series, this three-pole fixed circuit breaker combines a 2500 A rated current with the advanced PR122/P-LSI electronic overcurrent release.
The PR122/P-LSI release provides long-time, short-time and instantaneous overcurrent protection, allowing the circuit breaker to protect conductors, switchboards and downstream equipment against overloads and short circuits. Adjustable electronic protection functions make the E3V2500 suitable for coordinated protection schemes in demanding industrial and commercial electrical installations.
This configuration is a three-pole fixed circuit breaker with rear horizontal terminals. The E3V performance level is intended for applications requiring substantial short-circuit breaking capability, while the fixed construction provides a robust solution for permanent installation within main switchboards and power-distribution assemblies.
Key Advantages
- High-current 2500 A SACE Emax air circuit breaker for demanding power-distribution systems.
- PR122/P-LSI electronic overcurrent release provides comprehensive LSI circuit protection.
- Long-time, short-time and instantaneous protection functions support selective protection schemes.
- Three-pole fixed configuration for permanent switchboard installation.
- Rear horizontal terminals support practical connection to switchboard busbar systems.
- High E3V short-circuit performance for installations with substantial prospective fault currents.

Reliable Protection for High-Current Power Distribution
Air circuit breakers such as the ABB SACE Emax E3V2500 provide switching and overcurrent protection at main incomer and feeder levels within low-voltage distribution systems. The PR122/P-LSI electronic release continuously evaluates circuit current and can initiate tripping when programmed overload, short-time or instantaneous protection thresholds are exceeded.
The inclusion of short-time protection in the LSI release provides greater flexibility for discrimination and selectivity between upstream and downstream protective devices than an LI-only configuration. This makes the 1SDA056660R1 particularly suitable for complex industrial switchboards where continuity of supply and coordinated fault protection are important.
Typical Applications
- Main low-voltage distribution switchboards.
- Industrial power-distribution systems.
- Manufacturing and process plants.
- Commercial and infrastructure electrical installations.
- Transformer secondary and main incomer protection.
- High-current feeder protection.
- Power distribution and control assemblies.
