1SDA071985R1 ABB E6.2H/f 5000 Ekip Touch LSI 4p FHR Air Circuit Breaker

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

The ABB E6.2H/f 5000 Ekip Touch LSI 4p FHR, order code 1SDA071985R1, is a high-capacity four-pole air circuit breaker (ACB) from the ABB SACE Emax 2 range. Designed for demanding low-voltage power distribution, it combines a 5000 A rated uninterrupted current with a full-size neutral and high short-circuit performance for industrial, commercial and infrastructure switchboards.

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

The E6.2H/f 5000 is a fixed four-pole breaker with full-size neutral and rear horizontal terminals. Its H performance level provides an ultimate short-circuit breaking capacity of 100 kA at 400 V AC, making it suitable for high-current incoming supplies, transformer circuits and critical main distribution switchboards where strong fault-clearing performance and selective protection are required.

Key Advantages

• Very high 5000 A rated uninterrupted current for major low-voltage distribution systems.
• Four-pole configuration with full-size neutral for demanding four-wire electrical networks.
• Advanced Ekip Touch LSI electronic trip unit for adjustable circuit protection.

Selective High-Current Protection with a Full-Size Neutral

Air circuit breakers such as the ABB SACE Emax 2 E6.2H/f provide protection, switching and isolation for high-current low-voltage electrical networks. The full-size neutral configuration is particularly suitable for four-wire distribution systems where the neutral conductor requires the same current-carrying capability as the phase conductors.

The Ekip Touch LSI trip unit combines long-time overload, short-time selective and instantaneous short-circuit protection. Together with the breaker's 5000 A current rating and 100 kA short-circuit breaking capability at 400 V AC, the 1SDA071985R1 provides a robust solution for critical distribution systems requiring very high current capacity, selective coordination and dependable electronic protection.

Typical Applications

• Industrial low-voltage main distribution switchboards.
• Manufacturing plants and large production facilities.
• Transformer protection and distribution systems.
• Generator and critical power distribution systems.
• Data centres and high-availability infrastructure.
• Commercial and infrastructure power distribution.
• High-current incoming supply protection.
• Four-wire distribution systems requiring a full-size neutral and selective LSI protection.
