1SDA072272R1 ABB E2.2N 1000 Ekip Dip LSI 3p WMP Air Circuit Breaker 1000 A

Why Choose the ABB E2.2N 1000 Ekip Dip LSI 3p WMP Air Circuit Breaker?

The ABB E2.2N 1000 Ekip Dip LSI 3p WMP, order code 1SDA072272R1, is a high-performance three-pole air circuit breaker from the ABB SACE Emax 2 range, designed for protection and switching in low-voltage electrical distribution systems. Rated at 1000 A, it combines the E2.2N frame with ABB's solid-state Ekip Dip LSI electronic trip unit for dependable long-time overload, short-time delayed and instantaneous short-circuit protection.

The Ekip Dip LSI release provides three fundamental protection functions for effective coordination within industrial and commercial power networks. Long-time protection safeguards against sustained overloads, short-time delayed protection supports selectivity between upstream and downstream protective devices, and instantaneous protection responds rapidly to severe short-circuit faults.

With a rated uninterrupted current of 1000 A, rated operational voltage of 690 V AC and rated ultimate short-circuit breaking capacity of 66 kA at 400 V AC, the 1SDA072272R1 is suited to demanding power distribution applications. Its withdrawable moving-part construction enables installation with a compatible Emax 2 E2.2 fixed part and facilitates inspection, servicing and replacement within electrical switchboards.

Selective Protection for Low-Voltage Power Distribution

Air circuit breakers such as the ABB SACE Emax 2 provide switching and protection for high-current low-voltage distribution circuits. The E2.2N combines substantial short-circuit interruption capability with electronic protection, helping safeguard cables, busbars, switchgear and connected equipment against damaging overload and short-circuit conditions.

The Ekip Dip LSI release combines long-time overload protection with short-time delayed and instantaneous short-circuit protection. The short-time delay function enables improved coordination between protective devices, helping isolate a fault at the appropriate point in the distribution network while maintaining supply to unaffected circuits where the system has been designed for selectivity.

Typical Applications

• Main low-voltage electrical distribution switchboards.
• Industrial power distribution systems.
• Transformer and installation protection.
• Commercial building electrical infrastructure.
• Manufacturing and process plant switchgear.
• Critical power distribution systems.
• Infrastructure and utility installations.
• Three-phase AC distribution networks requiring selective LSI protection.
