1SDA057123R1 ABB E6V 5000 PR122/P-LI 5000A 3P Withdrawable Air Circuit Breaker

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

The ABB 1SDA057123R1 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-LI R5000 electronic overcurrent release providing long-time overload and instantaneous short-circuit protection.

As part of the proven ABB SACE Emax series, the E6V 5000 combines high short-circuit performance with a withdrawable design suited to critical switchboard applications. The moving part can be installed with the corresponding Emax fixed part, allowing isolation and removal of the breaker for inspection, servicing or replacement.

The PR122/P-LI electronic trip unit provides adjustable long-time and instantaneous protection for high-current distribution circuits. Combined with the E6V frame and 5000 A rating, this configuration is well suited to major incoming, transformer secondary and high-capacity feeder applications.

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 instantaneous short-circuit thresholds are exceeded, helping protect busbars, cables, transformers and connected electrical equipment.

The PR122/P-LI release combines long-time overload and instantaneous short-circuit protection with the high-current capability of the E6V frame. Its withdrawable construction also allows the breaker moving part to be isolated and removed from its associated fixed part, supporting maintainability and continuity strategies in critical power distribution installations.

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 high-current circuit breakers.
