1SDA070995R1 ABB E2.2N 1600 Ekip Touch LSI 3p F HR Air Circuit Breaker 1600 A

Why Choose the ABB E2.2N 1600 Ekip Touch LSI 3p F HR Air Circuit Breaker?

The ABB E2.2N 1600 Ekip Touch LSI 3p F HR, order code 1SDA070995R1, is a high-performance 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 E2.2N frame provides a rated uninterrupted current of 1600 A and a rated operational voltage of 690 V AC, making it suitable for high-current feeders, incomers and main distribution circuits.

This model is equipped with an Ekip Touch LSI solid-state electronic trip unit, providing long-time overload (L), short-time short-circuit (S) and instantaneous short-circuit (I) protection. The addition of short-time protection enables improved selectivity and coordination between protective devices, while the Ekip Touch interface provides advanced configuration and monitoring capabilities for modern intelligent switchboards.

The E2.2N performance class provides a rated ultimate short-circuit breaking capacity of 66 kA at 400 V AC. The 1SDA070995R1 is a three-pole fixed circuit breaker with rear horizontal terminals and is fitted with four auxiliary change-over contacts plus open/closed circuit-breaker position indication for integration into compatible low-voltage switchgear.

Selective LSI Protection for 1600 A Power Distribution

Air circuit breakers such as the ABB SACE Emax 2 E2.2N provide switching, isolation and protection for high-current low-voltage electrical networks. With a 1600 A current rating and 66 kA short-circuit breaking capacity at 400 V AC, the E2.2N 1600 is suited to distribution systems where substantial load currents and prospective fault levels must be safely controlled.

The Ekip Touch LSI trip unit provides three complementary electronic protection functions. Long-time protection responds to sustained overloads, short-time protection allows delayed fault clearing to improve selectivity with downstream devices, and instantaneous protection rapidly interrupts severe short circuits. This combination makes the 1SDA070995R1 particularly suitable for coordinated industrial and commercial distribution networks where selective protection is important.

Typical Applications

• Main low-voltage distribution switchboards.
• Industrial power distribution systems.
• Transformer secondary protection.
• High-current feeder and incomer protection.
• Manufacturing and process plant switchgear.
• Commercial and infrastructure electrical installations.
• Building services and utility distribution boards.
• Distribution systems requiring selective LSI protection and high short-circuit performance.
