1SDA071895R1 ABB E6.2H 5000 Ekip Touch LSI 4p FHR Air Circuit Breaker

Why Choose the ABB E6.2H 5000 Ekip Touch LSI 4p FHR Air Circuit Breaker?

The ABB E6.2H 5000 Ekip Touch LSI 4p FHR, order code 1SDA071895R1, is a high-performance four-pole air circuit breaker (ACB) designed for protection, switching and isolation in demanding low-voltage power distribution systems. Part of the ABB SACE Emax 2 series, it combines a substantial 5000 A rated current with high short-circuit performance for major industrial, commercial and infrastructure installations.

This Emax 2 circuit breaker incorporates the Ekip Touch LSI electronic trip unit, providing long-time overload, short-time selective short-circuit and instantaneous short-circuit protection. The addition of short-time protection supports selective coordination between protective devices, helping isolate faults while maintaining continuity elsewhere in the electrical distribution network.

The E6.2H 5000 is a fixed, four-pole breaker with rear horizontal terminals. The E6.2H performance level provides an ultimate short-circuit breaking capacity of 100 kA at 380–440 V AC, with service breaking capacity equal to 100% of Icu at these voltages, making it suitable for high-current incoming supplies, transformer circuits and critical main distribution switchboards.

Selective High-Current Circuit Protection for Power Distribution

Air circuit breakers such as the ABB SACE Emax 2 E6.2H provide protection, switching and isolation for high-current low-voltage electrical networks. By detecting overload and short-circuit conditions, the breaker can disconnect the affected circuit to help protect cables, switchgear and connected equipment while supporting dependable operation of the wider distribution system.

The Ekip Touch LSI trip unit adds short-time selective protection to long-time overload and instantaneous short-circuit protection, allowing more sophisticated coordination between upstream and downstream devices. Combined with the E6.2H frame's 5000 A current rating and 100 kA breaking performance at 380–440 V AC, the 1SDA071895R1 is particularly suited to critical high-power distribution applications.

Typical Applications

• Industrial low-voltage main distribution switchboards.
• Manufacturing plants and large production facilities.
• Transformer protection and distribution systems.
• Generator protection and distribution systems.
• Commercial building electrical distribution systems.
• Data centres and critical power infrastructure.
• Utilities and infrastructure installations.
• High-current incoming supplies and feeders requiring selective short-circuit protection.
