1SDA072072R1 ABB E1.2N 630 Ekip Dip LSI 3p WMP Air Circuit Breaker

Why Choose the ABB E1.2N 630 Ekip Dip LSI 3p WMP Air Circuit Breaker?

The ABB E1.2N 630 Ekip Dip LSI 3p WMP, order code 1SDA072072R1, is a compact air circuit breaker (ACB) moving part from the ABB SACE Emax 2 series, designed for switching and protection in low-voltage power distribution systems. With a rated uninterrupted current of 630 A, three-pole construction and ABB's Ekip Dip electronic trip technology, it provides dependable circuit protection for industrial, commercial and infrastructure installations.

The Ekip Dip LSI solid-state electronic trip unit provides long-time overload, short-time delayed short-circuit and instantaneous short-circuit protection. The addition of short-time protection compared with an LI release gives engineers greater flexibility when coordinating upstream and downstream protective devices, helping support selective operation in appropriately designed electrical distribution systems.

The 1SDA072072R1 is the withdrawable moving part (WMP) of the Emax 2 E1.2 circuit breaker system and is designed for use with the corresponding fixed part. The E1.2N performance level combines the compact dimensions of the E1.2 frame with high short-circuit performance, making this breaker well suited to switchboards where dependable protection, selectivity and convenient maintenance are important.

Selective Electronic Protection for Low-Voltage Distribution

Air circuit breakers such as the ABB SACE Emax 2 E1.2N provide switching, isolation and protection for low-voltage electrical distribution circuits. The compact E1.2 frame combines substantial short-circuit performance with a withdrawable architecture, allowing the moving part to be disconnected from its corresponding fixed part for inspection, maintenance or replacement.

The Ekip Dip LSI electronic trip unit combines adjustable long-time overload, short-time delayed short-circuit and instantaneous short-circuit protection. The short-time function provides additional flexibility for selective protection schemes, helping engineers coordinate the breaker with downstream protective devices while retaining rapid instantaneous operation for severe short-circuit conditions.

Typical Applications

• Low-voltage power distribution switchboards.
• Industrial electrical distribution systems.
• Commercial building power distribution.
• Manufacturing and process installations.
• Incoming and feeder circuit protection.
