1SDA073045R1 ABB E2.2N 2500 Ekip Touch LSI 4p WMP Air Circuit Breaker

Why Choose the ABB E2.2N 2500 Ekip Touch LSI 4p WMP Air Circuit Breaker?

The ABB 1SDA073045R1 is a high-current SACE Emax 2 E2.2N air circuit breaker moving part rated at 2500 A, designed for protection, switching and isolation in demanding low-voltage power distribution systems. This four-pole withdrawable model incorporates the Ekip Touch LSI electronic trip unit, providing long-time, short-time and instantaneous protection.

The Ekip Touch platform combines configurable electronic protection with an intuitive touchscreen interface for convenient adjustment and access to electrical information. Its LSI protection functions support selective coordination between upstream and downstream devices, making the breaker well suited to main incomers, high-current feeders and other critical distribution circuits.

With a rated uninterrupted current of 2500 A, a four-pole configuration and rated operational voltage of 690 V AC, the E2.2N provides an ultimate short-circuit breaking capacity of 66 kA at 400 V AC. The withdrawable moving-part design connects to a separate chassis part and facilitates inspection, maintenance and replacement in serviceable switchboard installations.
