1SDA061319R1 ABB E6L-A 5000 PR122/P-LSIG 5000 A 3-Pole Air Circuit Breaker

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

The ABB E6L-A 5000 PR122/P-LSIG, order code 1SDA061319R1, is a high-performance three-pole air circuit breaker (ACB) 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-LSIG electronic overcurrent release, providing long-time overload (L), selective short-circuit (S), instantaneous short-circuit (I) and ground-fault (G) protection. These comprehensive protection functions enable accurate circuit protection and support selective coordination within complex low-voltage distribution networks.

The 1SDA061319R1 is a fixed three-pole version with horizontal rear terminals. The E6L-A 5000 platform provides a short-circuit breaking capacity of 150 kA at 480 V AC and a short-time withstand current of 100 kA, making it suitable for high-fault-level power distribution systems where dependable protection and high interrupting performance are essential.

Reliable Protection for High-Current Distribution Systems

Air circuit breakers such as the ABB E6L-A protect major low-voltage distribution circuits against overload, short-circuit and ground-fault conditions while providing dependable switching and isolation. The PR122/P electronic release continuously monitors electrical conditions and commands the breaker to trip according to its configured protection thresholds when abnormal current conditions occur.

The LSIG configuration provides comprehensive protection by combining long-time overload, selective short-time, instantaneous and ground-fault functions. Together with the high interrupting capability of the E6L-A platform, this makes the 1SDA061319R1 particularly suitable for critical high-capacity switchboards and power distribution systems requiring selective and dependable circuit protection.

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 electrical substations.
• Generator and transformer distribution systems.
• Applications requiring comprehensive LSIG overcurrent and ground-fault protection.
