1SDA072903R1 ABB E2.2N 1000 Ekip Dip LSIG 4p WMP Air Circuit Breaker

Why Choose the ABB 1SDA072903R1 E2.2N 1000 Ekip Dip LSIG 4p WMP Air Circuit Breaker?

The ABB 1SDA072903R1 is a high-performance SACE Emax 2 E2.2N four-pole air circuit breaker moving part designed for protection and switching in demanding low-voltage electrical distribution systems. Rated at 1000 A, this withdrawable breaker combines the robust E2.2N frame with an Ekip Dip LSIG electronic protection release.

The Ekip Dip LSIG trip unit provides long-time (L), short-time (S), instantaneous (I) and earth-fault (G) protection, helping protect electrical installations against overloads, short circuits and earth faults. Protection parameters are adjustable through DIP switches, enabling the breaker to be configured for the requirements of the protected distribution circuit.

With a rated operational voltage of up to 690 V AC and a rated ultimate short-circuit breaking capacity of 66 kA across key low-voltage system voltages, the E2.2N provides substantial fault-interruption capability. Its four-pole withdrawable moving-part (WMP) construction supports maintainable switchboard designs for industrial, commercial and infrastructure power-distribution applications.

Advanced Protection for Low-Voltage Power Distribution

Air circuit breakers such as the ABB SACE Emax 2 E2.2N provide high-current switching and protection for low-voltage distribution networks. The Ekip Dip LSIG electronic release combines long-time overload, short-time selective short-circuit, instantaneous short-circuit and earth-fault protection, helping safeguard cables, switchgear and connected equipment against damaging electrical faults.

The E2.2N frame combines strong short-circuit performance with ABB's withdrawable Emax 2 architecture. This allows the breaker moving part to be removed from its corresponding fixed section for servicing or replacement, making the 1SDA072903R1 well suited to switchboards where protection performance, maintainability and continuity of operation are important.

Typical Applications

• Low-voltage main distribution switchboards.
• Industrial power distribution systems.
• Commercial and infrastructure electrical distribution.
• Transformer secondary protection and switching.
• Generator and utility distribution systems.
• Manufacturing and process plant switchgear.
