1SDA072292R1 ABB E2.2H 1000 Ekip Dip LSI 3-Pole Air Circuit Breaker

Why Choose the ABB 1SDA072292R1 E2.2H 1000 Ekip Dip LSI Air Circuit Breaker?

The ABB 1SDA072292R1 is a high-performance SACE Emax 2 E2.2H air circuit breaker designed for reliable switching and protection in demanding low-voltage electrical distribution systems. This three-pole withdrawable moving-part configuration has a rated uninterrupted current of 1000 A and incorporates the Ekip Dip LSI electronic trip unit.

As part of the ABB SACE Emax 2 range, the E2.2H combines substantial short-circuit performance with adjustable electronic protection for industrial, commercial and infrastructure switchboards. The Ekip Dip LSI release provides long-time overload, short-time delayed short-circuit and instantaneous short-circuit protection, allowing coordinated protection of feeders and distribution circuits.

The E2.2H 1000 provides a rated ultimate short-circuit breaking capacity of 100 kA at 400 V AC, 50 Hz and an E2.2H short-time withstand capability of 85 kA. Its withdrawable moving-part construction connects through a separate chassis part, supporting efficient inspection, servicing and replacement in compatible ABB Emax 2 switchgear.

High-Performance Selective Protection for Low-Voltage Distribution

Air circuit breakers such as the ABB Emax 2 E2.2H provide essential switching and fault protection for high-current low-voltage networks. The Ekip Dip LSI electronic release provides long-time protection against sustained overloads, short-time delayed protection for short-circuit coordination and instantaneous protection against severe fault currents, helping safeguard cables, switchgear and connected electrical equipment.

The adjustable short-time protection function makes the LSI configuration particularly useful where protection selectivity between upstream and downstream devices is required. Combined with the E2.2H's high short-circuit performance and withdrawable architecture, the 1SDA072292R1 provides a maintainable protection solution for demanding industrial and commercial distribution systems.
