1SDA071611R1 ABB E2.2B 1600 Ekip Dip LI 4-Pole Fixed Air Circuit Breaker

Why Choose the ABB E2.2B 1600 Ekip Dip LI 4p FHR Air Circuit Breaker?

The ABB E2.2B 1600 Ekip Dip LI 4p FHR, order code 1SDA071611R1, is a SACE Emax 2 air circuit breaker (ACB) designed for switching and protection in low-voltage AC power distribution systems. This fixed four-pole E2.2B breaker combines a 1600 A rated current with ABB's Ekip Dip LI solid-state electronic trip unit and rear horizontal main terminals.

The Ekip Dip LI release provides long-time overload (L) and instantaneous short-circuit (I) protection. This straightforward electronic protection configuration is well suited to installations requiring dependable overload and high-level short-circuit protection without the additional short-time or ground-fault functions provided by LSI and LSIG releases.

The E2.2B performance level provides an ultimate short-circuit breaking capacity of 42 kA at 440 V AC, together with a rated short-time withstand current of 42 kA for 1 s. ABB documentation also specifies 42 kA Icu at 690 V AC for this E2.2B configuration, making the 1SDA071611R1 a robust solution for industrial and commercial distribution boards operating at voltages up to 690 V AC.
