Why Choose the ABB E3L2000 PR122/P-LSIG Air Circuit Breaker?
The ABB E3L2000 PR122/P-LSIG, order code 1SDA056733R1, is a high-performance SACE Emax air circuit breaker (ACB) designed for comprehensive protection and switching in high-current low-voltage power-distribution systems. Part of the ABB SACE Emax E3 series, this four-pole fixed circuit breaker combines a 2000 A rated uninterrupted current with the advanced PR122/P-LSIG R2000 electronic overcurrent release.
The PR122/P-LSIG release provides long-time, short-time, instantaneous and earth-fault protection. These LSIG protection functions help safeguard conductors, switchboards and downstream equipment against sustained overloads, short circuits and earth faults while supporting coordinated protection and selective fault clearing across complex electrical distribution networks.
This configuration is a four-pole fixed circuit breaker with rear horizontal terminals, designed for permanent integration into low-voltage switchboards. With a rated operational voltage of 690 V AC and an ultimate short-circuit breaking capacity of 130 kA at 400 V AC, the E3L2000 is well suited to demanding industrial and infrastructure power systems.
