1SDA071027R1 ABB E2.2B 2000 Ekip G Touch LSIG 3p F HR Air Circuit Breaker 2000 A

Why Choose the ABB E2.2B 2000 Ekip G Touch LSIG 3p F HR Air Circuit Breaker?

The ABB E2.2B 2000 Ekip G Touch LSIG 3p F HR, order code 1SDA071027R1, is a 2000 A air circuit breaker (ACB) from the ABB SACE Emax 2 range, designed for generator and high-current low-voltage power distribution applications. Its E2.2 frame combines fixed three-pole construction with electronic protection and rear horizontal connections for permanent integration into compatible switchboards.

This model is equipped with an Ekip G Touch LSIG solid-state electronic trip unit, combining generator-oriented functionality with long-time overload (L), short-time short-circuit (S), instantaneous short-circuit (I) and ground-fault (G) protection. The Ekip G Touch platform is particularly suited to generator-fed networks where comprehensive protection, monitoring and coordination are required.

The E2.2B performance class provides a rated ultimate short-circuit breaking capacity of 42 kA at 415 V AC and 42 kA at 690 V AC, together with a rated short-time withstand current of 42 kA for 1 s. The 1SDA071027R1 is supplied with four auxiliary contacts, a trip signalling contact and circuit-breaker open/closed position indication.

Generator-Oriented LSIG Protection for High-Current Power Systems

Air circuit breakers such as the ABB SACE Emax 2 E2.2B provide switching, isolation and protection for high-current low-voltage electrical networks. With a rated uninterrupted current of 2000 A, 42 kA breaking capacity at both 415 V AC and 690 V AC and a 42 kA short-time withstand rating for 1 s, this breaker provides robust protection for generator-fed and general distribution systems.

The Ekip G Touch LSIG trip unit combines generator-oriented functionality with four complementary protection functions. Long-time protection responds to sustained overloads, short-time protection supports selective coordination, instantaneous protection rapidly interrupts severe short circuits, and ground-fault protection detects potentially damaging earth-fault currents. This makes the 1SDA071027R1 particularly suitable for generator switchboards and sophisticated power systems requiring comprehensive electronic protection.

Typical Applications

• Generator protection and generator switchboards.
• Main low-voltage distribution switchboards.
• Transformer and installation protection.
• Industrial power distribution systems.
• High-current feeder and incomer protection.
• Critical and standby power systems.
• Manufacturing and process plant switchgear.
• Networks requiring selective LSIG and integrated ground-fault protection.
