1SDA071665R1 ABB E2.2N 2000 Ekip Touch LSI 4p F HR Air Circuit Breaker 2000 A

Why Choose the ABB E2.2N 2000 Ekip Touch LSI 4p F HR Air Circuit Breaker?

The ABB E2.2N 2000 Ekip Touch LSI 4p F HR, order code 1SDA071665R1, is a high-performance four-pole air circuit breaker (ACB) designed for switching and protection in high-current low-voltage electrical distribution systems. Part of the ABB SACE Emax 2 series, it combines a 2000 A rated current with an Ekip Touch LSI electronic trip unit for configurable overload, selective short-circuit and instantaneous short-circuit protection.

The Ekip Touch LSI release provides long-time, short-time and instantaneous protection functions through a touch-sensitive interface. Long-time protection is adjustable from 0.4–1 × In, selective short-circuit protection from 0.6–10 × In and instantaneous protection from 1.5–15 × In, allowing the breaker to be coordinated precisely with the characteristics of the protected electrical system.

With a rated operational voltage of 690 V AC, four-pole configuration and fixed construction with rear horizontal terminals, the E2.2N 2000 is designed for integration into low-voltage switchboards. Its N performance level provides a rated ultimate short-circuit breaking capacity of 66 kA from 380–690 V AC, making it a robust solution for industrial, commercial and infrastructure power distribution.

Selective Protection for High-Current Power Distribution

Air circuit breakers such as the ABB SACE Emax 2 provide switching, isolation and protection for high-current low-voltage distribution circuits. With its 2000 A current rating and 66 kA short-circuit breaking capacity, the E2.2N 2000 helps protect switchboards, cables, transformers and connected electrical equipment against overloads and severe short-circuit conditions.

The Ekip Touch LSI electronic release adds selective short-time protection to long-time overload and instantaneous protection. This enables more sophisticated coordination between protective devices, helping downstream breakers clear localised faults before an upstream breaker operates and thereby supporting continuity of supply across correctly coordinated electrical distribution systems.

Typical Applications

• Low-voltage main distribution switchboards.
• Industrial electrical distribution systems.
• Commercial building power distribution.
• Manufacturing and process plants.
• Transformer secondary protection.
• Incoming and outgoing distribution feeders.
• Infrastructure and utility installations.
• Power distribution systems requiring selective short-circuit coordination.
