1SDA071952R1 ABB E6.2H/f 4000 Ekip Dip LSI 4p F HR Air Circuit Breaker

Why Choose the ABB E6.2H/f 4000 Ekip Dip LSI 4p F HR Air Circuit Breaker?

The ABB E6.2H/f 4000 Ekip Dip LSI 4p F HR, order code 1SDA071952R1, is a high-performance 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, this fixed circuit breaker combines a high current rating with electronic protection for industrial, commercial and infrastructure power distribution applications.

This E6.2H/f breaker incorporates the Ekip Dip LSI solid-state electronic trip unit, providing long-time overload, short-time short-circuit and instantaneous short-circuit protection. The adjustable electronic protection functions allow the breaker to be configured to suit the characteristics and protection requirements of the electrical installation.

With a rated uninterrupted current of 4000 A, a four-pole full-size neutral configuration and rated operational voltage up to 690 V AC, the 1SDA071952R1 is designed for high-current distribution systems. Its E6.2H performance level provides a rated ultimate short-circuit breaking capacity of 100 kA at 440 V AC, while the fixed construction and rear horizontal terminals support integration into low-voltage switchboards.

Reliable Protection for High-Current Power Distribution

Air circuit breakers such as the ABB SACE Emax 2 E6.2H/f provide switching, isolation and protection for major low-voltage electrical distribution circuits. Their high continuous-current and short-circuit ratings make them particularly suitable for main switchboards, incoming supplies and other points in an installation where substantial electrical loads and prospective fault currents are present.

The Ekip Dip LSI electronic trip unit allows long-time, short-time and instantaneous protection functions to be adjusted for the installation. Combined with the Emax 2 platform's high short-time withstand capability, this helps engineers coordinate protection and maintain selectivity across complex low-voltage distribution networks.

Typical Applications

• Main incoming protection in low-voltage switchboards.
• Industrial power distribution systems.
• Large commercial and infrastructure installations.
• Manufacturing and process plants.
• Power distribution centres and main switchgear.
• Transformer secondary and generator distribution systems.
• High-current electrical distribution and protection applications.
