1SDA072355R1 ABB E2.2S 1600 Ekip Touch LSI 3-Pole Air Circuit Breaker

Why Choose the ABB 1SDA072355R1 E2.2S 1600 Ekip Touch LSI Air Circuit Breaker?

The ABB 1SDA072355R1 is a high-performance SACE Emax 2 E2.2S air circuit breaker designed for reliable protection and switching in demanding low-voltage electrical distribution systems. This three-pole withdrawable moving-part configuration has a rated uninterrupted current of 1600 A and incorporates the advanced Ekip Touch LSI electronic trip unit.

The Ekip Touch LSI release provides long-time overload, short-time short-circuit and instantaneous short-circuit protection. Combining adjustable electronic protection with the Ekip Touch interface, this configuration is well suited to distribution systems where protection coordination, system monitoring and straightforward access to breaker functions are important.

The E2.2S 1600 performance level provides a rated ultimate short-circuit breaking capacity of 85 kA at 440 V AC and a rated short-time withstand current of 66 kA for 1 s. Its withdrawable moving-part construction supports maintainable switchboard designs by allowing the breaker assembly to be removed from its compatible fixed part for servicing or replacement.

Advanced LSI Protection for Low-Voltage Power Distribution

The ABB Emax 2 E2.2S combines high-current switching with advanced electronic protection for demanding low-voltage networks. Its Ekip Touch LSI trip unit provides long-time protection against sustained overloads, short-time protection for coordinated short-circuit clearing and instantaneous protection against severe fault currents, helping protect cables, busbars, switchgear and connected equipment.

The short-time protection function makes this LSI configuration particularly suitable for systems where selectivity between upstream and downstream protective devices is important. Combined with an 85 kA ultimate breaking capacity at 440 V AC, 66 kA short-time withstand capability and ABB's withdrawable Emax 2 architecture, the 1SDA072355R1 provides a robust and maintainable solution for critical power-distribution applications.
