1SDA057167R1 ABB E6V6300 PR123/P-LSIG 6300A 4-Pole Withdrawable Air Circuit Breaker Moving Part

Why Choose the ABB E6V6300 PR123/P-LSIG 6300A 4-Pole Withdrawable Air Circuit Breaker?

The ABB 1SDA057167R1 is a high-performance SACE Emax E6V air circuit breaker moving part 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 substantial 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 withdrawable circuit breaker moving part is equipped with 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 E6V6300 provides a rated operational voltage of 690 V AC and an ultimate short-circuit breaking capacity of 150 kA at 400 V AC, 50 Hz. Combined with its 6300 A current capability, four-pole construction and withdrawable moving-part design, the 1SDA057167R1 is engineered for major distribution systems requiring high fault-clearing performance, neutral switching and maintainable switchgear.

Advanced Protection for Very High-Current Power Distribution

Air circuit breakers such as the ABB SACE Emax E6V6300 provide switching 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 combines long-time, selective short-circuit, instantaneous and earth-fault protection functions for sophisticated electrical distribution networks. Together with the E6V6300's 6300 A current capability, four-pole construction, 150 kA ultimate short-circuit breaking capacity at 400 V AC and withdrawable design, the 1SDA057167R1 is particularly suited to critical installations requiring comprehensive protection and serviceable switchgear.

Typical Applications

• Low-voltage main distribution switchboards.
• Withdrawable industrial switchgear assemblies.
• Very high-current incoming and feeder circuits.
• Manufacturing and process plants.
• Commercial and infrastructure power distribution.
• Transformer secondary protection and switching.
• Generator and utility distribution systems.
• Four-wire electrical systems requiring neutral switching and earth-fault protection.
