1SDA072249R1 ABB E2.2N 800 Ekip Hi-Touch LSIG 3-Pole Air Circuit Breaker

Why Choose the ABB 1SDA072249R1 E2.2N 800 Ekip Hi-Touch LSIG Air Circuit Breaker?

The ABB 1SDA072249R1 is a high-performance SACE Emax 2 E2.2N air circuit breaker designed for protection and switching in demanding low-voltage electrical distribution systems. This three-pole withdrawable moving-part configuration has a rated uninterrupted current of 800 A and incorporates the advanced Ekip Hi-Touch LSIG electronic trip unit.

As part of the ABB SACE Emax 2 range, the E2.2N combines high breaking performance with sophisticated electronic protection for industrial, commercial and infrastructure switchboards. The Ekip Hi-Touch LSIG release provides long-time overload, short-time short-circuit, instantaneous short-circuit and earth-fault protection, while its touchscreen-based interface supports intuitive configuration and monitoring.

With a rated operational voltage of 690 V AC and a rated ultimate short-circuit breaking capacity of 66 kA at 400 V AC, the E2.2N 800 is engineered for high-performance distribution applications. Its withdrawable construction connects through a separate chassis part, allowing the breaker moving assembly to be removed from compatible Emax 2 switchgear for inspection, servicing or replacement.
