1SDA057124R1 ABB E6V 5000 PR122/P-LSI 5000A 3P Withdrawable Air Circuit Breaker

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

The ABB 1SDA057124R1 is a high-performance SACE Emax E6V air circuit breaker moving part designed for protection and switching in demanding high-current low-voltage electrical distribution systems. Rated at 5000 A, this three-pole withdrawable 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 a withdrawable design suited to critical switchboard applications. The moving part is designed for use with the corresponding Emax fixed part, allowing isolation and removal of the breaker for inspection, servicing or replacement.

With a rated operational voltage of 690 V AC, an ultimate short-circuit breaking capacity of 150 kA at 415 V AC and 100 kA at 690 V AC, the E6V provides robust performance where substantial prospective fault currents are present. Its 100 kA short-time withstand current for 1 s further supports selective protection in high-capacity distribution networks.

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, combined with withdrawable construction, makes this breaker particularly suitable for high-capacity distribution systems requiring both high fault performance and maintainability.

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.
• Switchboards requiring withdrawable breakers with high breaking capacity and LSI protection.
