1SDA071532R1 ABB E2.2S 800 Ekip Dip LSI 4-Pole Air Circuit Breaker

Why Choose the ABB 1SDA071532R1 E2.2S 800 Ekip Dip LSI Air Circuit Breaker?

The ABB 1SDA071532R1 is a SACE Emax 2 E2.2S air circuit breaker designed for reliable protection and switching in demanding low-voltage power distribution systems. Rated at 800 A, this four-pole fixed breaker combines ABB's E2.2S frame with an Ekip Dip LSI solid-state electronic trip unit.

The Ekip Dip LSI release provides long-time overload (L), short-time selective short-circuit (S) and instantaneous short-circuit (I) protection. Its adjustable electronic protection functions support coordinated protection strategies in industrial and commercial distribution systems without integrated earth-fault protection.

The 1SDA071532R1 is supplied in a fixed four-pole configuration with rear horizontal terminals. With an 800 A rated current, 85 kA ultimate short-circuit breaking capacity at 440 V AC and 66 kA short-time withstand current for 1 s, it provides substantial fault-handling capability for critical switchboard incomer and feeder applications.

Selective LSI Protection for Demanding Power Distribution

The ABB SACE Emax 2 E2.2S platform is engineered for low-voltage switchboards requiring substantial fault interruption and short-time withstand performance. The combination of an 800 A current rating, 85 kA Icu at 440 V AC and 66 kA Icw for 1 s makes the 1SDA071532R1 particularly suitable for distribution systems where high prospective fault currents and protection selectivity must be accommodated.

Its Ekip Dip LSI electronic release protects against sustained overloads, delayed short circuits and severe instantaneous short circuits. The fixed four-pole construction and rear horizontal terminals make the breaker suitable for integration into appropriately designed switchboards, while four auxiliary contacts and open/closed position indication support electrical control and status monitoring.

Typical Applications

• Low-voltage main switchboard incomers.
• Industrial power distribution systems.
• Commercial building electrical distribution.
• Transformer secondary protection.
• Feeder and sub-distribution protection.
• Manufacturing and process facilities.
• Infrastructure and utility installations.
• Systems requiring high short-circuit breaking capacity.
• Distribution networks requiring selective LSI protection.
