1SDA071703R1 ABB E2.2S 2500 Ekip Dip LSIG 4p FHR Air Circuit Breaker

Why Choose the ABB E2.2S 2500 Ekip Dip LSIG 4p FHR Air Circuit Breaker?

The ABB E2.2S 2500 Ekip Dip LSIG 4p FHR, order code 1SDA071703R1, is a high-performance four-pole air circuit breaker (ACB) from the ABB SACE Emax 2 range, designed for protection and control of high-current low-voltage electrical distribution systems. Combining a 2500 A rated uninterrupted current with an Ekip Dip LSIG electronic trip unit, it provides comprehensive long-time overload, selective short-circuit, instantaneous short-circuit and earth-fault protection.

This E2.2S circuit breaker is supplied in a fixed four-pole configuration with rear horizontal terminals. Its Ekip Dip LSIG solid-state electronic release provides adjustable protection through straightforward DIP-switch settings, allowing key protection parameters to be configured efficiently during commissioning and maintenance without requiring a touch-interface trip unit.

With an S short-circuit performance level and a rated ultimate short-circuit breaking capacity of 85 kA at 400/415 V AC, the 1SDA071703R1 is engineered for substantial power distribution duties. It maintains a breaking capacity of 66 kA at 690 V AC and provides a rated short-time withstand current of 66 kA for 1 second, supporting robust protection and selective coordination in demanding low-voltage networks.
