1SDA071959R1 ABB E6.2H/f 4000 Ekip Hi-Touch LSIG 4p FHR Air Circuit Breaker

Why Choose the ABB E6.2H/f 4000 Ekip Hi-Touch LSIG 4p FHR Air Circuit Breaker?

The ABB E6.2H/f 4000 Ekip Hi-Touch LSIG 4p FHR, order code 1SDA071959R1, is a high-performance four-pole air circuit breaker (ACB) from the ABB SACE Emax 2 range. Designed for demanding low-voltage power distribution, it combines a 4000 A rated uninterrupted current with a fully rated fourth pole and high short-circuit performance for industrial, commercial and infrastructure switchboards.

This Emax 2 circuit breaker incorporates the Ekip Hi-Touch LSIG electronic trip unit, providing long-time overload, short-time selective short-circuit, instantaneous short-circuit and earth-fault protection. This comprehensive LSIG protection supports selective coordination while adding dedicated earth-fault protection for critical electrical distribution networks.

The E6.2H/f 4000 is a fixed four-pole breaker with a fully rated fourth pole and rear horizontal connections. Its H performance level provides an ultimate short-circuit breaking capacity of 100 kA at 440 V AC together with a rated short-time withstand current of 100 kA for 1 s, making it suitable for high-current distribution systems with demanding fault-level, selectivity and earth-fault protection requirements.

Fully Rated Four-Pole LSIG Protection for Power Distribution

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 fully rated four-pole construction is particularly suited to four-wire distribution systems where the fourth pole requires the same current capability as the phase poles.

The Ekip Hi-Touch LSIG trip unit combines long-time overload, short-time selective, instantaneous short-circuit and earth-fault protection. Together with the breaker's 4000 A current rating, 100 kA breaking capacity at 440 V AC and 100 kA short-time withstand capability, the 1SDA071959R1 provides a robust solution for critical distribution systems requiring high fault performance, selective coordination and comprehensive earth-fault 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-fault-level incoming supply protection.
• Four-wire distribution systems requiring a fully rated fourth pole and LSIG protection.
