1SDA057108R1 ABB E6V 5000 PR122/P-LSI 5000A 3P Fixed Air Circuit Breaker

Why Choose the ABB E6V 5000 PR122/P-LSI 5000A 3P Fixed Air Circuit Breaker?

The ABB 1SDA057108R1 is a high-performance SACE Emax E6V air circuit breaker designed for protection and switching in demanding high-current low-voltage electrical distribution systems. Rated at 5000 A, this three-pole fixed breaker incorporates an ABB PR122/P-LSI R5000 electronic overcurrent release providing long-time overload, short-time delayed and instantaneous short-circuit protection.

As part of the proven ABB SACE Emax series, the E6V 5000 combines exceptional short-circuit performance with robust fixed switchboard construction. Its rear horizontal terminals provide a practical connection arrangement for permanent integration into industrial, infrastructure, utility and large commercial low-voltage distribution assemblies.

The E6V performance level provides an ultimate short-circuit breaking capacity of 150 kA at 415 V AC, 130 kA at 500 V AC and 100 kA at 690 V AC. Combined with a 100 kA short-time withstand current for 1 s, the breaker is well suited to major incoming and feeder circuits with high prospective fault currents.

High-Performance Protection for Critical Power Distribution

Air circuit breakers such as the ABB SACE Emax E6V provide switching and overcurrent protection for major low-voltage distribution circuits. The electronic trip unit monitors current conditions and initiates circuit-breaker operation when configured overload or short-circuit thresholds are exceeded, helping protect busbars, cables, transformers and connected electrical equipment.

The PR122/P-LSI release combines long-time overload, short-time delayed short-circuit and instantaneous short-circuit protection with the exceptional fault-interruption capability of the E6V frame. Its 150 kA Icu at 415 V AC makes this breaker particularly suitable for high-capacity distribution systems where very high prospective short-circuit currents can occur.

Typical Applications

• Main incoming circuit breakers in high-current low-voltage switchboards.
• Industrial power distribution systems.
• High-capacity feeder protection.
• Transformer secondary protection and switching.
• Manufacturing and process plants.
• Commercial and infrastructure power distribution.
• Generator and utility distribution systems.
• Fixed switchboard installations requiring high breaking capacity and LSI protection.
