ABB 1SDA072362R1 E2.2H 1600 Ekip Dip LSI 3p WMP 100kA Air Circuit Breaker

The ABB 1SDA072362R1 is an air circuit breaker component: the withdrawable moving part for a SACE Emax 2 E2.2H 1600, three-pole, Ekip Dip LSI electronic release. Rated 1600 A uninterrupted current, 100 kA breaking capacity at 400 V AC. It ships without a fixed part — a matching cradle must be ordered separately for switchboard installation.

Selection Notes

The LSI release adds the S (short-time delay) function to the standard L (overload) and I (instantaneous) protections, so this moving part can be set to hold off tripping briefly on a downstream fault and let a smaller breaker clear it first — useful when this unit sits upstream of other Emax 2 breakers in a selective coordination scheme. At 100 kA Icu and 85 kA Icw for 1 s, the E2.2H frame covers higher prospective fault currents than the lower N performance level in the same frame size. Because this is a WMP (moving part only), it is not a complete breaker on its own: order the matching fixed part (cradle) to rack it into a switchboard, which is the usual choice when standardizing spares across several draw-out Emax 2 positions. Pick the 4-pole version instead if the installation needs a switched or disconnectable neutral.
