1SDA073003R1 ABB E2.2B 2000 Ekip Dip LSIG 4p WMP Air Circuit Breaker 2000 A

Why Choose the ABB E2.2B 2000 Ekip Dip LSIG 4p WMP Air Circuit Breaker?

The ABB E2.2B 2000 Ekip Dip LSIG 4p WMP, order code 1SDA073003R1, is a four-pole air circuit breaker (ACB) moving part designed for protection, switching and isolation in high-current low-voltage electrical distribution systems. Part of the ABB SACE Emax 2 series, it combines a 2000 A rated uninterrupted current with electronic circuit protection for industrial, commercial and infrastructure power distribution applications.

This Emax 2 circuit breaker is equipped with the Ekip Dip LSIG solid-state electronic trip unit, providing long-time, short-time, instantaneous and ground-fault protection. The LSIG configuration delivers comprehensive protection against sustained overloads, short circuits and earth-fault conditions, while adjustable protection settings support coordination with other protective devices throughout the electrical distribution system.

The E2.2B 2000 provides a rated ultimate short-circuit breaking capacity of 42 kA at 400–440 V AC and a rated short-time withstand current of 42 kA for 1 s. Its four-pole withdrawable moving-part (WMP) construction is designed for use with the corresponding Emax 2 fixed part, facilitating isolation, inspection, servicing and replacement within maintainable switchgear assemblies.
