Why Choose the ABB E4S4000 PR122/P-LSIG Air Circuit Breaker?
The ABB E4S4000 PR122/P-LSIG, order code 1SDA056797R1, is a high-current SACE Emax air circuit breaker (ACB) designed for switching and comprehensive circuit protection in demanding low-voltage power-distribution systems. Part of the ABB SACE Emax E4 series, this four-pole fixed circuit breaker combines a 4000 A rated current with the advanced PR122/P-LSIG R4000 electronic overcurrent release.
The PR122/P-LSIG release provides long-time overload, short-time short-circuit, instantaneous short-circuit and earth-fault protection. These LSIG functions provide comprehensive protection against sustained overloads, short circuits and earth faults while supporting selective coordination across complex industrial, commercial and infrastructure power-distribution networks.
This configuration is a four-pole fixed circuit breaker with rear horizontal terminals. The breaker is supplied with four auxiliary contacts and circuit-breaker open/closed position indication, supporting integration into high-capacity switchboards where dependable protection, status monitoring and permanent busbar connection are required.
