1SDA072026R1 ABB E6.2V/f 6300 Ekip Touch LSIG 4p F HR Air Circuit Breaker

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

The ABB E6.2V/f 6300 Ekip Touch LSIG 4p F HR, order code 1SDA072026R1, 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 provides robust high-current protection for major switchboards, incoming supplies and critical industrial distribution networks.

This E6.2V/f breaker incorporates an Ekip Touch LSIG electronic trip unit, providing long-time overload (L), short-time short-circuit (S), instantaneous short-circuit (I) and ground-fault (G) protection. The integrated electronic release provides adjustable protection settings and comprehensive fault coverage, helping engineers achieve effective coordination throughout complex electrical distribution systems.

The breaker is supplied in a fixed four-pole configuration with full-size neutral and rear flat horizontal terminals. Its V performance level delivers a rated ultimate short-circuit breaking capacity of 150 kA at 400–440 V AC, while maintaining 100 kA at 690 V AC, making it suitable for high-power installations with substantial prospective fault currents.

Advanced LSIG 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, short circuits and ground faults while providing a controllable switching point within the electrical installation. The combination of a 6300 A current rating and V-level short-circuit performance makes this breaker particularly suitable for main distribution positions where substantial load and prospective fault currents can occur.

The Ekip Touch LSIG electronic trip unit provides adjustable long-time, short-time, instantaneous and ground-fault protection, enabling engineers to coordinate the breaker with upstream and downstream protective devices. Together with the E6.2V frame's high breaking and withstand capabilities, this provides a robust protection platform for sophisticated industrial, commercial 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 facilities.
• Commercial buildings and critical infrastructure installations.
• High-current feeder and distribution protection.
• Electrical networks requiring selective LSIG protection.
• Systems requiring integrated ground-fault protection.
