1SDA072300R1 ABB E2.2H 1000 Ekip G Hi-Touch LSIG 3p WMP Air Circuit Breaker

Why Choose the ABB E2.2H 1000 Ekip G Hi-Touch LSIG 3p WMP Air Circuit Breaker?

The ABB E2.2H 1000 Ekip G Hi-Touch LSIG 3p WMP, order code 1SDA072300R1, is a high-performance three-pole withdrawable air circuit breaker moving part from the ABB SACE Emax 2 range. Rated at 1000 A, it combines the high-breaking-capacity E2.2H frame with an advanced Ekip G Hi-Touch LSIG electronic trip unit for generator, transformer and demanding low-voltage distribution protection.

The Ekip G Hi-Touch LSIG release provides long-time overload, short-time delayed short-circuit, instantaneous short-circuit and ground-fault protection together with advanced generator-oriented protection, measurement and supervision capabilities. This makes the breaker particularly suitable for installations requiring sophisticated protection coordination, electrical monitoring and reliable management of generation and critical power systems.

The E2.2H performance class provides a rated ultimate short-circuit breaking capacity of 100 kA at 400–440 V AC and 85 kA at 500–690 V AC. It also provides a rated short-time withstand current of 85 kA for 1 s, supporting selective protection schemes in networks with high prospective fault currents.
