1SDA071907R1 ABB E6.2V 5000 Ekip G Touch LSIG 4p FHR Air Circuit Breaker

Why Choose the ABB E6.2V 5000 Ekip G Touch LSIG 4p FHR Air Circuit Breaker?

The ABB E6.2V 5000 Ekip G Touch LSIG 4p FHR, order code 1SDA071907R1, is a high-performance four-pole SACE Emax 2 air circuit breaker engineered for generator protection and demanding low-voltage power-distribution systems. Part of the ABB SACE Emax 2 E6.2 series, this fixed breaker combines a 5000 A rated uninterrupted current with the advanced Ekip G Touch LSIG electronic trip unit.

The E6.2V performance level delivers exceptional fault-interruption capability, with a rated ultimate short-circuit breaking capacity of 150 kA at 440 V AC and a rated short-time withstand current of 100 kA for 1 s. Its Ekip G Touch LSIG release combines long-time overload, selective short-time, instantaneous short-circuit and earth-fault protection with generator-oriented protection functionality.

This model is a fixed four-pole air circuit breaker equipped with rear flat horizontal (FHR) terminals. With a 690 V AC rating, four auxiliary changeover contacts and advanced Ekip Touch functionality, the 1SDA071907R1 is particularly suited to generator switchboards, standby power installations, industrial plants, data centres and other critical high-current distribution systems.

Advanced Generator Protection for High-Capacity Power Systems

Generator-fed networks require protection that can respond effectively to operating conditions that differ from conventional utility-fed distribution systems. The ABB E6.2V combines a 5000 A rated uninterrupted current, 150 kA ultimate breaking capacity at 440 V AC and 100 kA short-time withstand capability for 1 s, providing a robust platform for high-power generator and distribution circuits exposed to demanding fault conditions.

The Ekip G Touch LSIG trip unit combines generator-oriented functionality with comprehensive overload, short-circuit and earth-fault protection. Its touchscreen interface supports intuitive configuration and supervision, while the wider Emax 2 platform can be integrated with automation, communication and energy-management systems for sophisticated management of critical low-voltage electrical networks.

Typical Applications

• Generator protection and generator switchboards.
• Standby and emergency power-generation systems.
• Main incoming protection in high-current low-voltage switchboards.
• Industrial power-generation and distribution systems.
• Data centres and critical power infrastructure.
• Hospitals and essential-service electrical systems.
• Large manufacturing and process facilities.
• Multi-source electrical networks requiring advanced LSIG protection and selective coordination.
