1SDA061029R1 ABB E2S-A 800 PR122/P-LSI 800 A 3-Pole Withdrawable Air Circuit Breaker

Why Choose the ABB 1SDA061029R1 E2S-A 800 Air Circuit Breaker?

The ABB 1SDA061029R1 is a high-performance E2S-A 800 withdrawable air circuit breaker (ACB) moving part designed for protection and switching in demanding low-voltage power distribution systems. Part of the established ABB SACE Emax series, this three-pole breaker combines an 800 A rated current with the PR122/P electronic overcurrent release for dependable protection in industrial, commercial and infrastructure installations.

The breaker is equipped with an ABB PR122/P electronic trip unit with LSI protection functions, providing long-time overload, short-time short-circuit and instantaneous short-circuit protection. Its withdrawable moving-part construction supports convenient isolation, inspection, servicing and replacement when installed with a compatible ABB SACE Emax fixed part or cradle.

The E2S-A 800 configuration incorporates an R800 overcurrent release with an Im 12000 A designation. This UL three-pole moving part is also fitted with four auxiliary contacts and open/closed position indication, providing useful breaker-status signalling for integration into low-voltage switchgear and control systems.

Advanced Protection for Low-Voltage Power Distribution

Air circuit breakers such as the ABB E2S-A 800 provide switching and protection for high-current low-voltage distribution circuits. They are commonly used for incoming, feeder and distribution duties where dependable interruption of overload and short-circuit faults is essential for maintaining electrical system safety, availability and continuity of service.

The PR122/P electronic trip unit monitors circuit current and initiates breaker operation when configured protection thresholds are exceeded. Its LSI functionality provides short-time protection between the long-time and instantaneous functions, supporting selective coordination, while the withdrawable Emax construction facilitates servicing and breaker replacement within compatible switchgear assemblies.

Typical Applications

• Low-voltage main distribution switchboards.
• Industrial power distribution systems.
• Incoming and feeder circuit protection.
• Manufacturing and process plant electrical systems.
• Commercial and infrastructure power distribution.
• Withdrawable switchgear requiring selective and coordinated circuit protection.
