1SDA071969R1 ABB E6.2V/f 4000 Ekip Hi-Touch LSIG 4p F HR Air Circuit Breaker

Why Choose the ABB E6.2V/f 4000 Ekip Hi-Touch LSIG 4p F HR Air Circuit Breaker?

The ABB E6.2V/f 4000 Ekip Hi-Touch LSIG 4p F HR, order code 1SDA071969R1, is a high-performance air circuit breaker (ACB) from the ABB SACE Emax 2 series, designed for protection, switching and management of demanding low-voltage power distribution systems. Combining a 4000 A rated uninterrupted current with ABB's advanced Ekip Hi-Touch electronic trip technology, it is suited to major industrial, commercial and infrastructure installations.

The Ekip Hi-Touch LSIG solid-state electronic trip unit provides long-time overload, short-time short-circuit, instantaneous short-circuit and earth-fault protection. Its advanced protection, measurement and monitoring capabilities make the breaker particularly suitable for sophisticated distribution networks where precise protection coordination and detailed electrical system information are required.

This model features a four-pole full-size neutral configuration, fixed installation and rear horizontal terminals. The E6.2V/f performance level provides a rated ultimate short-circuit breaking capacity of 150 kA at 440 V AC and a rated short-time withstand current of 100 kA for 1 s, delivering robust protection for high-current and high-fault-level low-voltage systems.

Advanced LSIG Protection for High-Fault-Level Distribution

Air circuit breakers such as the ABB SACE Emax 2 E6.2V/f provide switching, isolation and protection for major low-voltage electrical distribution circuits. The high breaking performance of the V-class E6.2 platform makes this breaker particularly suitable for installations with substantial prospective fault currents, including major switchboards, transformer-fed systems and critical industrial distribution networks.

The Ekip Hi-Touch LSIG trip unit combines adjustable long-time, short-time, instantaneous and earth-fault protection with advanced measurement and monitoring functionality. Together with the breaker's high short-time withstand capability, these functions help engineers achieve effective protection coordination, selective tripping and detailed supervision of complex electrical distribution systems.

Typical Applications

• Main incoming protection in high-current 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-fault-level distribution networks requiring earth-fault protection.
