Why Choose the ABB E3L2000 PR122/P-LSI Air Circuit Breaker?
The ABB E3L2000 PR122/P-LSI, order code 1SDA056732R1, is a high-performance SACE Emax air circuit breaker (ACB) designed for switching and protection in demanding low-voltage power-distribution systems. Part of the ABB SACE Emax E3 series, this four-pole fixed circuit breaker combines a 2000 A rated current with the advanced PR122/P-LSI R2000 electronic overcurrent release.
The PR122/P-LSI release provides long-time, short-time and instantaneous overcurrent protection, helping protect conductors, switchboards and downstream equipment against overload and short-circuit conditions. Its electronic protection functions support accurate protection settings and coordinated fault clearing in industrial, commercial and infrastructure electrical distribution networks.
This configuration is a four-pole fixed circuit breaker with rear horizontal terminals and a rated operational voltage of 690 V AC. The E3L2000 provides a rated ultimate short-circuit breaking capacity of 130 kA at 400 V AC and is supplied with four auxiliary contacts and open/closed circuit-breaker position indication.
