1SDA073012R1 ABB E2.2N 2000 Ekip Dip LSI 4p WMP Air Circuit Breaker

Why Choose the ABB E2.2N 2000 Ekip Dip LSI 4p WMP Air Circuit Breaker?

The ABB 1SDA073012R1 is a SACE Emax 2 E2.2N air circuit breaker moving part rated at 2000 A, designed for reliable protection, switching and isolation in high-current low-voltage electrical distribution systems. This four-pole withdrawable model incorporates the Ekip Dip LSI electronic trip unit, providing adjustable long-time, short-time and instantaneous protection.

As part of the ABB SACE Emax 2 range, the E2.2N combines robust short-circuit performance with configurable electronic protection. The Ekip Dip LSI release uses DIP switches for straightforward protection adjustment, while its short-time function supports selective coordination between upstream and downstream protective devices.

With a rated uninterrupted current of 2000 A, a four-pole configuration and rated operational voltage up to 690 V AC, this E2.2N provides an ultimate short-circuit breaking capacity of 66 kA from 380 to 690 V AC. Its withdrawable moving-part construction supports efficient inspection, servicing and replacement in maintainable switchboard installations.

Selective LSI Protection for High-Current Power Distribution

The ABB SACE Emax 2 E2.2N platform provides dependable switching and protection for high-current low-voltage distribution networks. Its 66 kA ultimate short-circuit breaking capacity and short-time withstand capability support robust fault interruption and selective protection in main distribution circuits.

The Ekip Dip LSI release provides adjustable long-time protection against sustained overloads, short-time protection for selective fault coordination and instantaneous protection against severe short circuits. This combination enables engineers to coordinate protective devices so that faults can be isolated close to their source while helping maintain continuity in unaffected sections of the installation.

Typical Applications

• Main low-voltage switchboards and distribution boards.
• Industrial power distribution systems.
• Manufacturing plants and process facilities.
• Large commercial buildings and infrastructure installations.
• Transformer secondary and main incoming protection.
• High-current feeders requiring selective overload and short-circuit protection.
