1SDA071043R1 ABB E2.2S 2000 Ekip Dip LSIG 3p F HR Air Circuit Breaker 2000 A

Why Choose the ABB E2.2S 2000 Ekip Dip LSIG 3p F HR Air Circuit Breaker?

The ABB E2.2S 2000 Ekip Dip LSIG 3p F HR, order code 1SDA071043R1, is a high-performance 2000 A air circuit breaker (ACB) from the ABB SACE Emax 2 range, designed for switching, isolation and protection in demanding low-voltage power distribution systems. Its E2.2 frame combines a high continuous current rating with the S short-circuit performance class, making it suitable for industrial, commercial and infrastructure switchboards.

This model is equipped with an Ekip Dip LSIG solid-state electronic trip unit, providing long-time overload (L), short-time short-circuit (S), instantaneous short-circuit (I) and ground-fault (G) protection. This comprehensive protection package supports selective coordination while providing dedicated protection against earth-fault conditions in low-voltage distribution networks.

The E2.2S performance class provides a rated ultimate short-circuit breaking capacity of 85 kA at 400–440 V AC and 66 kA at 500–690 V AC. The 1SDA071043R1 is a three-pole fixed circuit breaker with rear flat horizontal terminals and is fitted with four auxiliary contacts plus open/closed circuit-breaker position indication for integration into compatible switchgear.

LSIG Protection for High-Current Power Distribution

Air circuit breakers such as the ABB SACE Emax 2 E2.2S provide switching, isolation and protection for high-current low-voltage electrical networks. With a rated uninterrupted current of 2000 A, an ultimate breaking capacity of 85 kA at 400–440 V AC and a rated short-time withstand current of 66 kA for 1 s, this breaker is designed for installations where substantial load currents and prospective fault levels must be safely managed.

The Ekip Dip LSIG trip unit provides four complementary electronic protection functions. Long-time protection responds to sustained overloads, short-time protection supports selective coordination with downstream devices, instantaneous protection rapidly interrupts severe short circuits, and ground-fault protection responds to potentially damaging earth-fault currents. This makes the 1SDA071043R1 suitable for coordinated distribution systems requiring comprehensive electronic circuit protection.

Typical Applications

• Main low-voltage distribution switchboards.
• Transformer secondary protection.
• Generator and installation protection.
• Industrial power distribution systems.
• High-current feeder and incomer protection.
• Manufacturing and process plant switchgear.
• Commercial and infrastructure electrical installations.
• Networks requiring selective LSIG protection and integrated ground-fault protection.
