1SDA071056R1 ABB E2.2H 2000 Ekip Touch LSIG 3p FHR Air Circuit Breaker

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

The ABB E2.2H 2000 Ekip Touch LSIG 3p FHR, order code 1SDA071056R1, is a high-performance air circuit breaker (ACB) designed for protection and control of low-voltage power distribution systems. As part of the advanced ABB Emax 2 circuit breaker series, it combines a 2000 A current rating with the intelligent Ekip 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 Touch LSIG trip unit provides adjustable protection against overloads, short circuits and earth faults, allowing protection settings to be coordinated with the requirements of the electrical distribution system.

With a rated operational voltage of up to 690 V AC, three-pole construction and fixed installation with rear horizontal terminals, the 1SDA071056R1 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 high levels of selectivity in demanding distribution networks.
