1SDA056723R1 ABB E3L2000 PR122/P-LI 2000 A 3-Pole Fixed Air Circuit Breaker

Why Choose the ABB E3L2000 PR122/P-LI 1SDA056723R1 Air Circuit Breaker?

The ABB 1SDA056723R1 is a high-performance SACE Emax E3 L air circuit breaker (ACB) designed for protection and switching in demanding low-voltage electrical distribution systems. This three-pole fixed breaker combines a 2000 A rated current with ABB's E3 L short-circuit performance class, making it suitable for industrial, commercial and infrastructure power distribution applications.

The E3L2000 is equipped with an ABB PR122/P-LI R2000 electronic overcurrent release, providing long-time overload and instantaneous short-circuit protection. The PR122/P platform provides electronic circuit protection and monitoring capabilities while the LI configuration focuses on the essential long-time and instantaneous protection functions required for many high-current distribution circuits.

With a 2000 A rating, three-pole fixed construction and rear horizontal terminals, the 1SDA056723R1 is designed for permanent integration into compatible SACE Emax low-voltage switchboards. Four auxiliary contacts and open/closed position indication further support integration into switchgear control, signalling and status-monitoring systems.
