1SDA073647R1 ABB E2.2S 250 Ekip G Hi-Touch LSIG 4p F HR Air Circuit Breaker 250 A

Why Choose the ABB E2.2S 250 Ekip G Hi-Touch LSIG 4p F HR Air Circuit Breaker?

The ABB E2.2S 250 Ekip G Hi-Touch LSIG 4p F HR, order code 1SDA073647R1, is a high-performance four-pole fixed air circuit breaker from the ABB SACE Emax 2 range, engineered specifically for advanced generator and low-voltage power distribution protection. Rated at 250 A, it combines the E2.2S frame with the sophisticated Ekip G Hi-Touch LSIG electronic trip unit.

The Ekip G Hi-Touch release provides long-time, short-time, instantaneous and earth-fault protection together with protection functions developed for generator applications. Integrated Ekip Measuring Pro and Network Analyzer functionality provide advanced electrical measurement and power-quality monitoring, while the touch-sensitive display gives operators direct access to protection settings and system information.

The E2.2S frame provides a rated ultimate short-circuit breaking capacity of 85 kA at 380–440 V AC and 66 kA at 500–690 V AC. Its fixed four-pole construction, 690 V AC rated operational voltage and rear horizontal terminals make the 1SDA073647R1 a capable solution for generator switchboards and demanding industrial, commercial and infrastructure distribution systems.

Advanced Generator LSIG Protection and Power Monitoring

Generator applications place specialised demands on circuit protection because fault-current behaviour and operating conditions can differ from conventional utility-fed distribution systems. The ABB E2.2S 250 with Ekip G Hi-Touch LSIG combines the established Emax 2 air circuit breaker platform with generator-specific protection functions, comprehensive LSIG protection and high short-circuit interruption performance.

The integrated Ekip Measuring Pro and Network Analyzer functions extend the breaker beyond conventional circuit protection by providing detailed electrical measurements and power-quality information. This combination makes the 1SDA073647R1 particularly suitable for generator switchboards and installations where protection, measurement and monitoring need to be integrated within a single circuit breaker platform.

Typical Applications

• Generator and generating-set switchboards.
• Generator protection in low-voltage power systems.
• Main and sub-main low-voltage distribution switchboards.
• Industrial manufacturing and process facilities.
• Critical infrastructure and standby power systems.
• Installations requiring advanced LSIG protection, electrical measurement and power-quality monitoring.
