Why Choose the ABB E3N-A 2000 PR123/P-LSIG 2000A 3P Air Circuit Breaker?
The ABB E3N-A 2000 PR123/P-LSIG, order code 1SDA057397R1, is a high-current SACE Emax air circuit breaker (ACB) designed for protection, switching and isolation in demanding low-voltage power distribution systems. Built on the ABB E3N-A platform, this three-pole breaker has a rated current of 2000 A and is intended for major industrial, commercial and infrastructure distribution circuits.
The breaker is equipped with the advanced ABB PR123/P-LSIG electronic overcurrent release. Its LSIG protection functions provide long-time overload, short-time short-circuit, instantaneous short-circuit and ground-fault protection, delivering comprehensive safeguarding for cables, busbars, switchgear and connected electrical equipment.
With its three-pole configuration, 2000 A rated current and N performance level, the E3N-A 2000 PR123/P-LSIG is suited to critical main incomer and high-current feeder duties. The advanced PR123/P release also provides greater protection functionality than basic LI or LSI releases, making this configuration particularly suitable where comprehensive fault protection and distribution-system coordination are required.
