1SDA073637R1 ABB E2.2S 250 Ekip G Hi-Touch LSIG 3p FHR Air Circuit Breaker 250 A

Why Choose the ABB E2.2S 250 Ekip G Hi-Touch LSIG 3p FHR Air Circuit Breaker?

The ABB E2.2S 250 Ekip G Hi-Touch LSIG 3p FHR, order code 1SDA073637R1, is a high-performance three-pole air circuit breaker (ACB) from the ABB SACE Emax 2 range, designed for advanced protection of generators and critical low-voltage power distribution systems. Rated at 250 A, it combines the E2.2 frame and S breaking-capacity level with ABB's sophisticated Ekip G Hi-Touch LSIG electronic trip unit.

The Ekip G Hi-Touch LSIG release provides long-time overload, short-time selective, instantaneous short-circuit and ground-fault protection together with protection functions specifically designed for generator applications. Integrated Ekip Measuring Pro and Network Analyzer functionality extends the breaker beyond conventional protection by providing advanced electrical measurement and power-quality monitoring.

The E2.2S 250 provides an ultimate short-circuit breaking capacity of 85 kA at 380–440 V AC and 66 kA at 500–690 V AC. This version is supplied as a fixed three-pole breaker with rear horizontal terminals and is suitable for systems operating at up to 690 V AC.

Advanced Generator and Critical Power Protection

Generator applications place specialised demands on circuit protection because generator fault currents and operating characteristics can differ significantly from utility-fed distribution systems. The Ekip G Hi-Touch platform is designed to address these requirements by combining conventional LSIG protection with generator-oriented protection, advanced measurements and network analysis.

With a 250 A current rating, breaking capacity of up to 85 kA and integrated Ekip Measuring Pro and Network Analyzer functionality, the E2.2S 250 Ekip G Hi-Touch LSIG provides a comprehensive platform for protecting, monitoring and managing generator-fed and other critical low-voltage power systems.

Typical Applications

• Generator protection and generator switchboards.
• Emergency and standby power systems.
• Low-voltage main distribution switchboards.
• Industrial power generation and distribution systems.
• Data centres and critical power infrastructure.
• Commercial and infrastructure electrical installations.
• Systems requiring advanced LSIG protection and ground-fault detection.
• Power networks requiring integrated measurement and power-quality analysis.
