1SDA061317R1 ABB E6L-A 5000 PR122/P-LSI 5000 A 3-Pole Air Circuit Breaker Moving Part

Why Choose the ABB E6L-A 5000 PR122/P-LSI Air Circuit Breaker?

The ABB E6L-A 5000 PR122/P-LSI, order code 1SDA061317R1, is a high-performance three-pole air circuit breaker (ACB) moving part designed for protection and switching of high-current low-voltage electrical distribution systems. As part of the proven ABB SACE Emax E6 series, it combines a 5000 A rated current with the advanced PR122/P electronic trip unit for dependable protection in demanding industrial, infrastructure and commercial power installations.

This E6L-A configuration uses the PR122/P-LSI electronic overcurrent release, providing long-time overload (L), selective short-circuit (S) and instantaneous short-circuit (I) protection. The electronic protection platform enables accurate circuit protection and supports selective coordination within complex low-voltage distribution networks.

The 1SDA061317R1 is a withdrawable three-pole moving-part version of the E6L-A 5000 breaker. Its withdrawable construction allows the breaker to be isolated and removed from the corresponding fixed part for servicing, inspection or replacement, making it particularly suitable for critical switchboards where maintainability and continuity of service are important.

Reliable Protection for High-Current Distribution Systems

Air circuit breakers such as the ABB E6L-A are designed to protect major low-voltage distribution circuits against overload and short-circuit conditions while providing dependable switching and isolation. The PR122/P electronic release monitors electrical conditions and initiates tripping according to the configured protection settings when abnormal current conditions occur.

The LSI protection configuration combines long-time overload protection with selective short-time and instantaneous short-circuit protection. Together with the withdrawable Emax construction, these functions make the E6L-A 5000 particularly well suited to high-capacity switchboards where selective protection, serviceability and dependable power distribution are essential.

Typical Applications

• Main incoming circuit protection in high-current low-voltage switchboards.
• Industrial power distribution systems.
• High-capacity feeder protection.
• Manufacturing and process plant switchgear.
• Commercial and infrastructure electrical distribution.
• Power distribution centres and substations.
