Why Choose the ABB E2S2000 PR123/P-LSIG Air Circuit Breaker?
The ABB E2S2000 PR123/P-LSIG, order code 1SDA056031R1, is a high-performance four-pole fixed air circuit breaker (ACB) 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 current of 2000 A with the advanced PR123/P-LSIG 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 across complex electrical distribution networks.
With a rated voltage of 690 V AC and an ultimate short-circuit breaking capacity of 85 kA at 400 V AC, the E2S2000 is suited to high-current switchboards and industrial power systems. This version uses fixed construction with rear horizontal terminals and is supplied with four change-over auxiliary contacts plus circuit-breaker open/closed position indication.
