The ABB 1SDA056773R1 is a high-performance SACE Emax E3L air circuit breaker moving part designed for reliable switching and protection in high-current low-voltage electrical distribution systems. Its product designation is E3L2500PR122/P-LSIGIn=2500A3pW, combining a 2500 A rated current, three-pole withdrawable construction and ABB's PR122/P-LSIG electronic overcurrent release.
As part of the ABB SACE Emax range, this E3L circuit breaker is engineered for demanding industrial, commercial and infrastructure power distribution applications. The PR122/P-LSIG electronic trip unit provides long-time, short-time, instantaneous and ground-fault protection functions, helping safeguard busbars, cables, switchgear and connected equipment against overloads, short circuits and earth faults.
The 1SDA056773R1 is the moving part of a three-pole withdrawable circuit breaker with a rated current of 2500 A. Its withdrawable execution supports efficient inspection, servicing and replacement within compatible SACE Emax switchgear, making it particularly suitable for major distribution systems where maintainability and comprehensive electronic protection are required.
Air circuit breakers such as the ABB SACE Emax E3L protect major low-voltage distribution circuits while providing dependable switching and isolation. Electronic protection releases monitor electrical conditions and initiate tripping when configured protection thresholds are exceeded, helping safeguard cables, busbars, switchgear and downstream equipment from potentially damaging fault currents.
The PR122/P-LSIG release fitted to the 1SDA056773R1 provides comprehensive protection against overload, short-time and instantaneous short-circuit conditions, together with ground-fault protection. Combined with its 2500 A current rating, three-pole construction and withdrawable execution, this E3L moving part is well suited to major distribution boards where advanced protection and convenient circuit-breaker maintenance are required.
