1SDA072975R1 ABB E2.2N 1600 Ekip Touch LSI 4p WMP Air Circuit Breaker 1600 A

Why Choose the ABB E2.2N 1600 Ekip Touch LSI 4p WMP Air Circuit Breaker?

The ABB E2.2N 1600 Ekip Touch LSI 4p WMP, order code 1SDA072975R1, is a four-pole air circuit breaker (ACB) moving part designed for protection, switching and isolation in low-voltage electrical distribution systems. Part of the ABB SACE Emax 2 series, it combines a 1600 A rated uninterrupted current with advanced electronic protection for industrial, commercial and infrastructure power distribution applications.

This Emax 2 circuit breaker is equipped with the Ekip Touch LSI solid-state electronic trip unit, providing long-time, short-time and instantaneous overcurrent protection. The Ekip Touch platform combines configurable electronic protection with an intuitive interface, while the LSI functions support overload protection, selective short-circuit coordination and rapid interruption of severe fault currents.

The E2.2N 1600 provides a rated ultimate short-circuit breaking capacity of 66 kA at 400 V AC and is rated for operation up to 690 V AC. Its four-pole withdrawable moving-part (WMP) construction is designed for use with the corresponding Emax 2 fixed part, supporting convenient isolation, inspection, servicing and replacement within maintainable switchgear assemblies.
