Why Choose the ABB E2S2000 PR123/P-LSIG Air Circuit Breaker Moving Part?
The ABB E2S2000 PR123/P-LSIG, order code 1SDA056047R1, is a high-performance four-pole withdrawable air circuit breaker moving part designed for switching and protection in demanding low-voltage power distribution systems. As part of the ABB SACE Emax E2 series, it combines a rated uninterrupted current of 2000 A with the advanced PR123/P-LSIG R2000 electronic overcurrent release.
The PR123/P-LSIG trip unit provides long-time, short-time, instantaneous and ground-fault protection. These LSIG protection functions help safeguard conductors, switchgear and connected equipment against overloads, short circuits and earth-fault conditions while supporting selective protection and coordination within complex industrial and commercial distribution networks.
This version is supplied as the moving part of a withdrawable E2S2000 circuit breaker and is intended for use with the appropriate ABB SACE Emax fixed part. Its four-pole construction, 2000 A current rating, 690 V AC rated voltage and 85 kA short-circuit breaking capacity at 400 V AC make it suitable for critical high-current switchboard applications.
