1SDA057005R1 ABB E6H 5000 PR122/P-LSIG 5000A 4-Pole Withdrawable Air Circuit Breaker

Why Choose the ABB E6H 5000 PR122/P-LSIG 5000A 4-Pole Withdrawable Air Circuit Breaker?

The ABB E6H 5000 PR122/P-LSIG, order code 1SDA057005R1, is a high-capacity SACE Emax air circuit breaker moving part designed for protection and switching in demanding low-voltage electrical distribution systems. Part of the ABB SACE Emax E6H series, this configuration combines a 5000 A rated current, four-pole construction and withdrawable execution with ABB's PR122/P electronic protection technology.

The breaker is equipped with a PR122/P-LSIG electronic overcurrent release, providing long-time, short-time, instantaneous and earth-fault protection functions. This comprehensive protection arrangement helps protect high-current distribution circuits against overloads, short circuits and earth faults while supporting selective coordination in complex electrical networks.

With a rated current of 5000 A, a four-pole configuration and withdrawable moving-part construction, the E6H 5000 PR122/P-LSIG is suited to main distribution switchboards and critical power systems where high breaking performance, comprehensive electronic protection and maintainability are required.
