1SDA072025R1 ABB E6.2V/f 6300 Ekip Touch LSI 4p F HR Air Circuit Breaker

Why Choose the ABB E6.2V/f 6300 Ekip Touch LSI 4p F HR Air Circuit Breaker?

The ABB E6.2V/f 6300 Ekip Touch LSI 4p F HR, order code 1SDA072025R1, is a high-performance four-pole fixed air circuit breaker (ACB) from the ABB SACE Emax 2 range, designed for protection and switching in demanding low-voltage power distribution systems. With a rated uninterrupted current of 6300 A, it is engineered for major switchboards, incoming supplies and high-current distribution circuits in industrial, commercial and infrastructure installations.

This E6.2V/f breaker incorporates an Ekip Touch LSI electronic trip unit, providing long-time overload (L), short-time short-circuit (S) and instantaneous short-circuit (I) protection. The Ekip Touch platform combines sophisticated electronic protection with an intuitive interface, supporting accurate configuration and coordination within complex electrical distribution networks.

The breaker is supplied in a fixed four-pole configuration with full-size neutral and rear horizontal terminals. Its V performance level provides a rated ultimate short-circuit breaking capacity of 150 kA at 400 V AC, making this 6300 A Emax 2 breaker suitable for installations where very high prospective fault currents demand robust interruption performance.

Reliable Protection for High-Current Power Distribution

Air circuit breakers such as the ABB Emax 2 E6.2V/f protect major low-voltage distribution circuits against overloads and short circuits while providing a robust switching point within the electrical installation. The combination of a 6300 A current rating and high V-level breaking performance makes this breaker particularly suitable for main distribution positions where substantial load and fault currents can occur.

The Ekip Touch LSI electronic trip unit provides adjustable long-time, short-time and instantaneous protection, enabling engineers to coordinate the breaker with upstream and downstream protection devices. This combination of high-current switching capability and configurable electronic protection supports reliable operation in sophisticated industrial and infrastructure power networks.

Typical Applications

• Main low-voltage switchboards and power distribution boards.
• High-current industrial power distribution systems.
• Transformer secondary and main incoming circuits.
• Large manufacturing and process plants.
• Commercial buildings and infrastructure installations.
• High-current feeder and distribution protection.
• Electrical networks requiring selective LSI protection.
• Installations with high prospective short-circuit currents.
