Why Choose the ABB E6H6300 PR123/P-LSIG 6300A 4-Pole Air Circuit Breaker?
The ABB 1SDA057023R1 is a high-performance SACE Emax E6H air circuit breaker (ACB) designed for protection and switching of very high-current low-voltage electrical distribution systems. As part of the ABB New Emax series, this E6H6300 combines a substantial 6300 A current rating with the advanced PR123/P-LSIG electronic overcurrent release for comprehensive circuit protection in demanding industrial, commercial and infrastructure installations.
This four-pole fixed circuit breaker features rear horizontal terminals and ABB's H short-circuit performance level. The PR123/P-LSIG electronic trip unit provides long-time overload (L), selective short-circuit (S), instantaneous short-circuit (I) and earth-fault (G) protection, making the breaker suitable for sophisticated electrical distribution networks requiring comprehensive protection and selective coordination.
With a rated current of 6300 A and an E6H short-circuit breaking performance of 100 kA, the 1SDA057023R1 is engineered for major power distribution applications where very high current capacity, robust fault protection and dependable switching are essential. Its four-pole construction enables switching and protection of the neutral conductor alongside all three phases.

Reliable Protection for High-Current Power Distribution
Air circuit breakers such as the ABB SACE Emax E6H6300 provide switching, isolation and protection for very high-current low-voltage distribution circuits. The electronic trip unit monitors electrical conditions and initiates circuit interruption when configured protection thresholds are exceeded, helping protect busbars, cables, transformers and connected equipment against damaging overload, short-circuit and earth-fault conditions.
The PR123/P-LSIG release provides comprehensive LSIG protection for sophisticated electrical distribution networks. Its combination of overload, selective short-circuit, instantaneous and earth-fault protection supports coordinated protection strategies, while the four-pole construction allows the neutral conductor to be switched together with the three phases. This makes the 1SDA057023R1 particularly suitable for critical high-capacity installations requiring comprehensive protection and dependable operation.
