1SDA072992R1 ABB E2.2H 1600 Ekip Dip LSI 4p WMP Air Circuit Breaker

Why Choose the ABB 1SDA072992R1 E2.2H 1600 Ekip Dip LSI 4p WMP Air Circuit Breaker?

The ABB 1SDA072992R1 is a high-performance SACE Emax 2 E2.2H four-pole air circuit breaker moving part designed for protection and switching in demanding low-voltage electrical distribution systems. Rated at 1600 A, this withdrawable breaker combines ABB's high-breaking-capacity E2.2H frame with an Ekip Dip LSI electronic protection release.

The Ekip Dip LSI release provides long-time (L) overload, short-time (S) selective short-circuit and instantaneous (I) short-circuit protection. The overload release is adjustable from 640–1600 A, the short-time delayed release from 960–16000 A and the instantaneous release from 2400–24000 A, supporting configurable and selective protection of distribution circuits.

The E2.2H performance level provides a rated ultimate short-circuit breaking capacity of 100 kA at 380–440 V AC and 85 kA at 500–690 V AC. Its four-pole withdrawable moving-part (WMP) construction, high fault-current capability and adjustable LSI protection make it suitable for industrial, commercial and infrastructure distribution systems where dependable protection and selectivity are required.
