Why Choose the ABB E6V6300 PR123/P-LSIG 6300A 4-Pole Air Circuit Breaker?
The ABB 1SDA057151R1 is a high-performance SACE Emax E6V air circuit breaker designed for protection and switching of very high-current low-voltage electrical distribution systems. Part of the ABB New Emax series, the E6V6300 combines a 6300 A current rating with the advanced PR123/P-LSIG electronic overcurrent release for comprehensive protection in demanding industrial, commercial and infrastructure power distribution applications.
This four-pole fixed circuit breaker features rear horizontal terminals and the PR123/P-LSIG R6300 electronic trip unit. Its LSIG protection functions provide long-time overload (L), selective short-circuit (S), instantaneous short-circuit (I) and earth-fault (G) protection, supporting sophisticated protection and selectivity requirements in high-capacity electrical networks.
The E6V designation identifies the high short-circuit performance version of the E6 frame. Combined with its substantial 6300 A current rating, four-pole construction, advanced PR123/P protection and fixed installation format, the 1SDA057151R1 is engineered for major power distribution systems where high fault-clearing capability, neutral switching and comprehensive circuit protection are required.
