The ABB E3S-A 1600 PR122/P-LSIG, order code 1SDA057485R1, is a high-performance SACE Emax air circuit breaker designed for switching and protection in demanding low-voltage power distribution systems. This E3S-A model has a rated current of 1600 A, three-pole construction and ABB's PR122/P-LSIG electronic overcurrent release.
The PR122/P-LSIG trip unit provides long-time, short-time, instantaneous and earth-fault protection. These LSIG functions provide comprehensive protection against overloads, short circuits and earth faults, helping safeguard cables, busbars, switchgear and connected equipment while supporting coordinated electrical distribution.
As part of the ABB SACE Emax family, the E3S-A combines robust air circuit breaker construction with configurable electronic protection. Its 1600 A current rating and three-pole configuration make it suitable for substantial three-phase distribution circuits, including main incomers, high-current feeders and bus-coupler applications.
Air circuit breakers such as the ABB SACE Emax E3S-A provide controlled switching and protection for high-current low-voltage distribution circuits. The electronic trip unit monitors electrical conditions and initiates tripping when configured protection thresholds are exceeded, helping limit damage caused by overloads, short circuits and earth faults.
The PR122/P-LSIG release combines four principal protection functions in one electronic trip unit, providing flexible protection for demanding distribution networks. Together with the robust E3S-A platform, this makes 1SDA057485R1 suitable for important distribution points where reliable fault interruption, protection coordination and continuity of electrical service are required.
