1SDA073636R1 ABB E2.2S 250 Ekip Hi-Touch LSIG 3p FHR Air Circuit Breaker 250 A

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

The ABB E2.2S 250 Ekip Hi-Touch LSIG 3p FHR, order code 1SDA073636R1, is a high-performance three-pole air circuit breaker (ACB) from the ABB SACE Emax 2 range, designed for advanced protection and switching in low-voltage power distribution systems. With a rated uninterrupted current of 250 A, it combines the E2.2 frame and S performance level with an advanced Ekip Hi-Touch LSIG electronic protection release.

The Ekip Hi-Touch LSIG release provides long-time overload, short-time short-circuit, instantaneous short-circuit and ground-fault protection. Its advanced electronic platform also supports measurement, monitoring and power-quality analysis functions, while the touch interface provides convenient access to protection settings and operating information for sophisticated electrical distribution applications.

The E2.2S performance level provides a rated ultimate short-circuit breaking capacity of 85 kA at 400/440 V AC and a rated short-time withstand current of 66 kA for 1 s. This three-pole model is supplied in a fixed configuration with rear horizontal terminals and includes four change-over auxiliary contacts together with circuit-breaker open/closed position indication.
