1SDA072592R1 ABB E6.2V 4000 Ekip Dip LSI 3P WMP Air Circuit Breaker

Why Choose the ABB 1SDA072592R1 E6.2V 4000 Ekip Dip LSI Air Circuit Breaker?

The ABB 1SDA072592R1 is a high-performance SACE Emax 2 E6.2V 4000 air circuit breaker moving part designed for protection and switching in demanding high-current low-voltage AC power distribution systems. Configured as an E6.2V 4000 Ekip Dip LSI 3p WMP, it combines a 4000 A rated current, three-pole construction and ABB's Ekip Dip electronic trip unit with LSI protection functions.

The E6.2V is a very-high-performance configuration within the ABB SACE Emax 2 family. This 4000 A model provides an ultimate short-circuit breaking capacity of 150 kA at 415 V AC and 100 kA at 690 V AC, providing the fault-interruption capability required for major distribution points with exceptionally high prospective short-circuit currents.

The Ekip Dip LSI electronic trip unit provides long-time overload, short-time short-circuit and instantaneous short-circuit protection. The addition of short-time protection supports selective coordination with downstream protective devices, while the three-pole withdrawable moving-part (WMP) architecture enables the breaker to be isolated and withdrawn from its separately ordered fixed part for inspection, maintenance or replacement.

Selective LSI Protection for Critical High-Current Distribution

Air circuit breakers such as the ABB Emax 2 E6.2V protect major low-voltage networks against overload and short-circuit conditions. With a 4000 A rated current and an ultimate short-circuit breaking capacity reaching 150 kA at 415 V AC, the 1SDA072592R1 is particularly suited to critical distribution points where very high prospective fault currents can occur.

The Ekip Dip LSI trip unit provides three complementary electronic protection functions. Long-time protection responds to sustained overloads, short-time protection introduces an adjustable short-circuit protection stage that can assist selectivity with downstream devices, and instantaneous protection rapidly interrupts severe short circuits. Combined with the E6.2V frame and withdrawable architecture, this provides a robust and maintainable solution for sophisticated high-current distribution systems.

Typical Applications

• Main incoming protection in high-current low-voltage switchboards.
• Industrial plants with very high prospective short-circuit currents.
• Transformer secondary protection.
• High-current distribution feeder protection.
• Data centres and critical-power installations.
• Large commercial and infrastructure electrical distribution.
• Manufacturing and process-industry switchgear.
• Utility and energy distribution installations.
• Systems requiring selective coordination between upstream and downstream protection.
• Withdrawable switchboards requiring high-performance LSI protection.
