1SDA057131R1 ABB E6V 5000 PR122/P-LI 5000A 4-Pole Withdrawable Air Circuit Breaker

Why Choose the ABB E6V 5000 PR122/P-LI 5000A 4-Pole Withdrawable Air Circuit Breaker?

The ABB E6V 5000 PR122/P-LI, order code 1SDA057131R1, is a high-capacity SACE Emax air circuit breaker moving part designed for protection and switching in demanding low-voltage electrical distribution systems. Part of the ABB SACE Emax E6V series, this configuration combines a 5000 A rated current, four-pole construction and withdrawable execution with ABB's PR122/P electronic protection technology.

The breaker is equipped with a PR122/P-LI R5000 electronic overcurrent release, providing long-time and instantaneous protection functions. This LI protection arrangement helps safeguard high-current distribution circuits against sustained overloads and severe short-circuit conditions while providing an electronic protection solution for major industrial and infrastructure electrical networks.

With a rated current of 5000 A, a four-pole configuration and withdrawable moving-part construction, the E6V 5000 PR122/P-LI is engineered for high-current switchgear where strong fault-interruption performance, maintainability and dependable circuit protection are required. The moving part is fitted with four auxiliary contacts and circuit-breaker open/closed position indication for integration into compatible SACE Emax switchgear.

Reliable LI Protection for High-Current Power Distribution

Air circuit breakers such as the ABB SACE Emax E6V provide switching, isolation and overcurrent protection for major low-voltage distribution circuits. The E6 frame supports very high operating currents, while the withdrawable architecture allows the circuit-breaker moving part to be used with compatible fixed equipment for easier inspection, servicing and replacement within high-capacity switchboards.

The PR122/P-LI electronic release provides long-time protection against sustained overload conditions together with instantaneous protection against severe short circuits. This combination is suitable where straightforward electronic overload and instantaneous fault protection is required without the additional short-time or earth-fault functions provided by LSI and LSIG trip-unit configurations.

Typical Applications

• Main low-voltage electrical distribution switchboards.
• Industrial manufacturing and process plants.
• High-current incomer and feeder protection.
• Transformer and generator distribution systems.
• Power generation and infrastructure installations.
• Withdrawable switchgear requiring electronic LI overcurrent protection.
