1SDA071953R1 ABB E6.2H/f 4000 Ekip Dip LSIG 4p F HR Air Circuit Breaker

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

The ABB E6.2H/f 4000 Ekip Dip LSIG 4p F HR, order code 1SDA071953R1, 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 comprehensive electronic protection for industrial, commercial and infrastructure electrical installations.

This E6.2H/f breaker incorporates the Ekip Dip LSIG solid-state electronic trip unit, providing long-time overload, short-time short-circuit, instantaneous short-circuit and earth-fault protection. The adjustable electronic protection functions allow the breaker to be coordinated with other protective devices and configured for the requirements of complex electrical distribution systems.

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 1SDA071953R1 is designed for high-current distribution systems. The E6.2H/f performance level provides a rated ultimate short-circuit breaking capacity of 100 kA at 440 V AC and a short-time withstand current of 100 kA for 1 s, while its fixed construction and rear horizontal terminals support integration into low-voltage switchboards.

Comprehensive LSIG Protection for High-Current 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 where substantial electrical loads and prospective fault currents are present.

The Ekip Dip LSIG electronic trip unit adds earth-fault protection to its long-time, short-time and instantaneous protection functions, providing comprehensive protection against the principal electrical fault conditions encountered in low-voltage distribution networks. Combined with the Emax 2 platform's high short-time withstand capability, this enables effective protection coordination and selectivity across complex installations.

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 and generator protection systems.
• High-current electrical distribution requiring earth-fault protection.
