1SDA056727R1 ABB E3L2000 PR123/P-LSIG 2000A 3P Fixed Air Circuit Breaker

Why Choose the ABB E3L2000 PR123/P-LSIG 2000A 3P Fixed Air Circuit Breaker?

The ABB E3L2000 PR123/P-LSIG, order code 1SDA056727R1, is a high-performance SACE Emax air circuit breaker (ACB) designed for advanced switching and protection in demanding low-voltage power distribution systems. Part of the ABB SACE Emax E3 series, this three-pole fixed breaker combines a 2000 A rated current with the advanced PR123/P-LSIG R2000 electronic overcurrent release.

The E3L2000 is supplied in a fixed three-pole configuration with horizontal rear terminals, providing a practical arrangement for busbar connections within industrial switchboards and power-distribution assemblies. Its PR123/P-LSIG electronic release provides long-time, short-time, instantaneous and earth-fault protection, helping safeguard busbars, cables, transformers and connected equipment against overloads, short circuits and earth faults.

Engineered for high-current applications where sophisticated protection, selectivity and system monitoring are important, the 1SDA056727R1 combines the proven E3L platform with ABB's advanced PR123/P electronic trip technology. The breaker is fitted with four auxiliary contacts and open/closed position indication, supporting integration with switchboard signalling, monitoring and control systems.
