1SDA071924R1 ABB E6.2H 6300 Ekip Touch LI 4p FHR Air Circuit Breaker 6300 A

Why Choose the ABB E6.2H 6300 Ekip Touch LI 4p FHR Air Circuit Breaker?

The ABB E6.2H 6300 Ekip Touch LI 4p FHR, order code 1SDA071924R1, is a high-current four-pole air circuit breaker (ACB) from the ABB SACE Emax 2 range. Designed for demanding low-voltage power distribution, it combines a 6300 A rated uninterrupted current with the E6.2H performance class and the advanced Ekip Touch LI electronic protection release.

The Ekip Touch LI electronic trip unit provides long-time overload and instantaneous short-circuit protection. Its colour touch interface supports intuitive protection configuration and monitoring, while the LI protection profile provides a straightforward solution for applications that do not require integrated short-time or earth-fault protection.

Rated for operation at up to 690 V AC, the E6.2H 6300 provides an ultimate short-circuit breaking capacity of 100 kA at 400 V AC. This version features a fixed four-pole construction with rear flat horizontal terminals, making it suitable for high-capacity industrial, commercial and infrastructure switchboards.

High-Current LI Protection for Power Distribution

The ABB E6.2H frame is designed for high-capacity low-voltage distribution systems where substantial continuous currents and high prospective fault levels must be managed. With a 6300 A rated current and 100 kA Icu at 400 V AC, the breaker provides robust protection for main switchboards, busbars, cables and other critical distribution equipment.

The Ekip Touch LI release combines long-time overload protection with instantaneous short-circuit protection. Its overload setting covers 2520–6300 A, while instantaneous protection covers 9450–94500 A. This makes the 1SDA071924R1 particularly suitable where configurable electronic LI protection and high breaking capacity are required without integrated short-time or earth-fault protection.
