Why Choose the ABB E3L2500 PR122/P-LI Air Circuit Breaker?
The ABB E3L2500 PR122/P-LI, order code 1SDA056763R1, is a high-performance SACE Emax air circuit breaker (ACB) designed for switching and overcurrent protection in demanding low-voltage power-distribution systems. Part of the ABB SACE Emax E3 series, this four-pole fixed circuit breaker combines a 2500 A rated uninterrupted current with the PR122/P-LI R2500 electronic overcurrent release.
The PR122/P-LI release provides long-time overload and instantaneous short-circuit protection. These LI protection functions help protect conductors, switchboards and downstream equipment against sustained overcurrents and severe short-circuit faults, making the breaker suitable for high-capacity industrial, commercial and infrastructure distribution networks.
This configuration is a four-pole fixed circuit breaker equipped with rear horizontal flat terminals. It features four auxiliary contacts arranged as 2 NO + 2 NC, open/closed position indication and an IP20 protection rating, while the E3L platform provides a rated ultimate short-circuit breaking capacity of 130 kA at 400 V AC.
