1SDA071732R1 ABB E4.2V 2000 Ekip Dip LSI 4p F HR Air Circuit Breaker 2000 A

Why Choose the ABB E4.2V 2000 Ekip Dip LSI 4p F HR Air Circuit Breaker?

The ABB E4.2V 2000 Ekip Dip LSI 4p F HR, order code 1SDA071732R1, is a high-performance four-pole air circuit breaker (ACB) designed for protection and switching in demanding low-voltage power distribution systems. As part of the advanced ABB SACE Emax 2 series, it combines a 2000 A rated uninterrupted current with an Ekip Dip LSI electronic protection release and the high short-circuit performance of the E4.2V frame.

This fixed circuit breaker incorporates the Ekip Dip LSI electronic trip unit, providing long-time overload, short-time short-circuit and instantaneous short-circuit protection. These LSI protection functions enable effective coordination within complex electrical distribution networks, helping protect cables, busbars, switchgear and connected equipment against overload and short-circuit conditions.

With a 150 kA ultimate short-circuit breaking capacity at 440 V AC and a 100 kA short-time withstand current for 1 s, the E4.2V 2000 is engineered for installations with exceptionally high prospective fault currents. This version features a fixed four-pole construction with rear horizontal connections, making it suitable for integration into high-capacity low-voltage switchboards and power distribution assemblies.

High-Capacity Protection for Critical Power Distribution

Air circuit breakers such as the ABB SACE Emax 2 protect high-current low-voltage distribution circuits against overloads and short circuits. The E4.2V frame is specifically suited to systems where exceptionally high prospective fault currents demand substantial breaking and short-time withstand capabilities, helping protect critical cables, busbars, switchgear and connected electrical equipment.

The Ekip Dip LSI electronic trip unit provides long-time, short-time and instantaneous protection, supporting coordinated protection across complex distribution networks. Combined with the E4.2V frame's 150 kA Icu at 440 V AC and 100 kA Icw for 1 s, the 1SDA071732R1 is particularly suited to main switchboards and high-power distribution systems where fault interruption capability and selective protection are essential.

Typical Applications

• Main low-voltage electrical distribution switchboards.
• High-fault-level industrial power distribution systems.
• Manufacturing and process facilities.
• Large commercial buildings and infrastructure installations.
• High-current feeder and distribution circuits.
• Transformer-fed low-voltage distribution systems.
• Critical power and utility distribution installations.
• Electrical switchgear and power distribution assemblies.
