1SDA061033R1 ABB E2S-A 800 PR122/P-LSIG 800A 3P Withdrawable Air Circuit Breaker

Why Choose the ABB E2S-A 800 PR122/P-LSIG 800A 3P Withdrawable Air Circuit Breaker?

The ABB E2S-A 800 PR122/P-LSIG, order code 1SDA061033R1, is a high-performance SACE Emax air circuit breaker moving part designed for protection and switching in demanding low-voltage power-distribution systems. Rated at 800 A, this three-pole E2S-A breaker combines robust high-current switching capability with ABB's advanced PR122/P-LSIG electronic overcurrent release.

This specific configuration is a withdrawable moving part (W MP), allowing the circuit breaker to be used with the appropriate SACE Emax fixed part for serviceable switchboard installations. The PR122/P-LSIG release provides long-time, short-time, instantaneous and earth-fault protection functions, delivering comprehensive LSIG protection against overloads, short circuits and earth faults.

With its 800 A rated current, three-pole configuration and S-performance E2 frame, the E2S-A is well suited to substantial industrial and commercial distribution circuits. The withdrawable design makes inspection, maintenance and breaker replacement more convenient in critical switchboards where continuity, maintainability and dependable protection are important.

Reliable Protection for Low-Voltage Power Distribution

Air circuit breakers such as the ABB SACE Emax E2S-A protect low-voltage electrical networks by monitoring current and interrupting the circuit when abnormal conditions exceed configured protection thresholds. The PR122/P-LSIG electronic release combines long-time overload protection with short-time and instantaneous short-circuit protection plus earth-fault protection, helping safeguard conductors, busbars, switchgear and connected equipment.

The withdrawable architecture is particularly useful in critical distribution boards because the breaker moving part can be isolated and removed from its compatible fixed part for inspection, servicing or replacement. Combined with its 800 A current rating and comprehensive electronic LSIG protection, the E2S-A provides a practical solution for maintainable industrial and commercial power-distribution systems.

Typical Applications

• Industrial low-voltage main distribution switchboards.
• Main incoming circuit protection.
• High-current feeder and distribution protection.
• Manufacturing and process-industry electrical systems.
• Commercial and infrastructure power distribution.
• Critical switchgear requiring maintainable withdrawable circuit breakers.
