1SDA061093R1 ABB E2H-A 800 PR122/P-LSI 800 A 3-Pole Withdrawable Air Circuit Breaker

Why Choose the ABB 1SDA061093R1 E2H-A 800 Air Circuit Breaker?

The ABB 1SDA061093R1 is a high-performance E2H-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. This protection combination supports selective coordination within distribution networks while providing rapid interruption when severe overcurrent conditions occur.

Its withdrawable moving-part execution is designed for use with a compatible ABB SACE Emax fixed part or cradle, allowing the breaker to be disconnected and withdrawn for inspection, servicing or replacement. The E2H-A performance level makes this 800 A breaker well suited to substantial incoming, feeder and distribution duties where reliable protection and maintainability are priorities.

Advanced Protection for Low-Voltage Power Distribution

Air circuit breakers such as the ABB E2H-A 800 provide switching and protection for high-current low-voltage distribution circuits. They are commonly applied to incoming, feeder and distribution circuits 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 adds short-time protection between the long-time and instantaneous functions, supporting selective coordination, while the withdrawable SACE Emax construction facilitates inspection, maintenance 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.
