1SDA057147R1 ABB E6V 6300 PR122/P-LI 6300A 4-Pole Fixed Air Circuit Breaker

Why Choose the ABB E6V 6300 PR122/P-LI 6300A 4-Pole Fixed Air Circuit Breaker?

The ABB E6V 6300 PR122/P-LI, order code 1SDA057147R1, is a high-capacity SACE Emax air circuit breaker designed for protection and switching in demanding low-voltage electrical distribution systems. Part of the ABB SACE Emax E6V series, this configuration combines a 6300 A rated current, four-pole construction and fixed execution with ABB's PR122/P electronic protection technology.

The breaker is equipped with a PR122/P-LI R6300 electronic overcurrent release, providing long-time and instantaneous protection functions. This LI protection arrangement helps protect very high-current distribution circuits against sustained overloads and severe short-circuit conditions while providing dependable electronic protection for major industrial, commercial and infrastructure electrical networks.

With a rated current of 6300 A, a four-pole configuration and fixed construction with rear horizontal terminals, the E6V 6300 PR122/P-LI is engineered for high-capacity switchboards with demanding prospective fault levels. The E6V performance class provides an ultimate short-circuit breaking capacity of 150 kA at 400 V AC, while four auxiliary change-over contacts and open/closed position indication support switchgear monitoring and control.
