1SDA057159R1 ABB E6V 6300 PR123/P-LSIG 6300 A 3-Pole Withdrawable Air Circuit Breaker

Why Choose the ABB 1SDA057159R1 E6V 6300 Air Circuit Breaker?

The ABB 1SDA057159R1 is a high-performance SACE Emax E6V air circuit breaker moving part designed for protection and switching in demanding low-voltage electrical distribution systems. Identified as E6V 6300 PR123/P-LSIG In=6300A 3p W MP, this three-pole withdrawable breaker configuration combines a 6300 A rated current with the advanced ABB PR123/P-LSIG electronic overcurrent release.

As part of the ABB SACE Emax / New Emax range, the E6V platform is engineered for installations requiring very high continuous current capacity and substantial short-circuit performance. The E6V breaking-capacity version provides an ultimate short-circuit breaking capacity of 150 kA at 400/415 V AC, making it suitable for major industrial switchboards, power distribution centres and infrastructure applications with high prospective fault currents.

The PR123/P-LSIG electronic trip unit provides long-time, short-time, instantaneous and earth-fault protection functions for comprehensive circuit protection. This configuration is a three-pole withdrawable moving part and is fitted with four auxiliary contacts together with circuit-breaker open/closed position indication for integration into compatible SACE Emax switchgear.

Advanced High-Current Circuit Protection

Air circuit breakers such as the ABB SACE Emax E6V provide switching, isolation and protection for high-current low-voltage electrical distribution systems. The E6V 6300 platform combines a 6300 A current rating with high short-circuit interruption capability, making it particularly well suited to main incoming supplies, busbar systems and major distribution feeders.

The PR123/P-LSIG electronic release provides comprehensive protection against overloads, delayed and instantaneous short circuits and earth faults. Combined with the withdrawable SACE Emax architecture, this provides a flexible solution for critical switchboards where protection performance, operational continuity and maintainability are important requirements.

Typical Applications

• Main low-voltage power distribution switchboards.
• High-current incoming and feeder circuits.
• Industrial electrical distribution systems.
• Power generation and utility installations.
• Large manufacturing and process facilities.
• Commercial and infrastructure power distribution.
• Data centres and critical power systems.
• Withdrawable switchgear requiring high short-circuit performance.
