1SDA061073R1 ABB E2S-A 1600 PR123/P-LSIG 1600 A 3-Pole Air Circuit Breaker Moving Part

Why Choose the ABB E2S-A 1600 PR123/P-LSIG Air Circuit Breaker?

The ABB E2S-A 1600 PR123/P-LSIG, order code 1SDA061073R1, is a high-performance three-pole SACE Emax air circuit breaker moving part designed for protection and control of high-current low-voltage electrical distribution systems. Part of the ABB SACE Emax E2 series, this UL version combines a 1600 A current rating with the advanced PR123/P electronic overcurrent release.

The integrated PR123/P-LSIG electronic trip unit provides long-time, short-time, instantaneous and earth-fault protection functions, supporting selective and dependable protection of industrial power distribution networks. The withdrawable moving-part configuration is particularly suitable for switchboards where ease of inspection, maintenance and replacement is important.

With a rated current of 1600 A, three-pole construction and an E2S-A frame with a 65 kA short-circuit rating at 480 V, this circuit breaker is engineered for demanding industrial distribution applications. It is supplied with four auxiliary contacts and circuit-breaker open/closed position indication.

Advanced Protection for Low-Voltage Distribution

Air circuit breakers such as the ABB SACE Emax E2S-A are used to protect high-current electrical distribution systems against abnormal current conditions. The electronic trip unit continuously supervises circuit conditions and initiates tripping when configured protection thresholds are exceeded.

The PR123/P-LSIG release provides comprehensive protection functionality for installations requiring coordinated long-time, short-time, instantaneous and earth-fault protection. Combined with the withdrawable Emax construction, it provides a practical solution for critical industrial switchboards where protection performance, serviceability and operational continuity are priorities.

Typical Applications

• Industrial low-voltage distribution switchboards.
• Main incoming and feeder circuit protection.
• Manufacturing and process plants.
• Power distribution centres.
• Commercial and infrastructure electrical systems.
• High-current machinery and automation distribution panels.
