1SDA071057R1 ABB E2.2H 2000 Ekip G Touch LSIG 3p FHR Air Circuit Breaker

Why Choose the ABB E2.2H 2000 Ekip G Touch LSIG 3p FHR Air Circuit Breaker?

The ABB E2.2H 2000 Ekip G Touch LSIG 3p FHR, order code 1SDA071057R1, is a high-performance air circuit breaker (ACB) designed for protection, switching and control of low-voltage power distribution systems. As part of the advanced ABB Emax 2 circuit breaker series, it combines a 2000 A rated current with the intelligent Ekip G Touch LSIG electronic protection trip unit for demanding industrial, commercial and infrastructure applications.

The E2.2H configuration provides high short-circuit performance, with a rated ultimate short-circuit breaking capacity of 100 kA at 400–440 V AC. Its Ekip G Touch LSIG electronic release provides long-time overload, short-time short-circuit, instantaneous short-circuit and earth-fault protection, while its generator-oriented functionality makes it particularly suitable for generator protection and power-generation applications.

With a rated operational voltage of up to 690 V AC, three-pole construction and fixed installation with rear horizontal terminals, the 1SDA071057R1 is designed for integration into low-voltage switchboards and power distribution assemblies. The breaker provides a rated short-time withstand current of 85 kA for 1 s, supporting selective protection coordination in demanding electrical networks.
