1SDA071645R1 ABB E2.2H 1600 Ekip Touch LSI 4p FHR Air Circuit Breaker

Why Choose the ABB E2.2H 1600 Ekip Touch LSI 4p FHR Air Circuit Breaker?

The ABB E2.2H 1600 Ekip Touch LSI 4p FHR, order code 1SDA071645R1, is a high-performance four-pole air circuit breaker (ACB) designed for demanding low-voltage power distribution systems. Part of the ABB SACE Emax 2 series, it combines a 1600 A rated current with the high-breaking-capacity E2.2H frame and advanced electronic protection for industrial, commercial and infrastructure installations.

The breaker is equipped with the Ekip Touch LSI electronic trip unit, providing long-time overload, short-time selective short-circuit and instantaneous short-circuit protection. Adjustable protection thresholds and the touch-sensitive display enable the breaker to be configured for coordinated distribution protection, while the short-time function supports selective operation between upstream and downstream protective devices.

The E2.2H frame provides an ultimate short-circuit breaking capacity of 100 kA at 380–440 V AC and 85 kA at 500–690 V AC. With a rated operational voltage of 690 V AC, rated insulation voltage of 1000 V AC and fixed four-pole construction with rear flat horizontal terminals, the 1SDA071645R1 is engineered for permanent integration into substantial low-voltage switchboards and busbar systems.

Advanced Selective Protection for Low-Voltage Power Distribution

Air circuit breakers used in high-current distribution systems must interrupt severe electrical faults while allowing protection settings to be coordinated across the installation. The ABB SACE Emax 2 E2.2H combines substantial short-circuit breaking performance with electronic protection, making it suitable for switchboards where both high fault levels and selective operation are important design considerations.

The Ekip Touch LSI release combines long-time overload, short-time selective and instantaneous short-circuit protection. The short-time protection stage provides additional flexibility compared with an LI release, allowing protection engineers to coordinate upstream and downstream devices so that, where correctly designed and configured, the protective device closest to a fault can operate before the upstream breaker.

Typical Applications

• Main low-voltage electrical distribution switchboards.
• Transformer-fed low-voltage distribution systems.
• Industrial power distribution systems.
• Commercial building electrical infrastructure.
• Manufacturing and process plant switchgear.
• Systems requiring selective short-circuit protection.
• Installations with high prospective short-circuit currents.
• OEM low-voltage switchgear and busbar assemblies.
