ABB 1SDA072621R1 E6.2V 5000 Ekip Dip LI 3p WMP 150kA Air Circuit Breaker

The ABB 1SDA072621R1 is the E6.2V 5000 Ekip Dip LI 3p WMP moving part for the SACE Emax 2 E6.2V air circuit breaker — a withdrawable insert rated 5000 A with a 150 kA breaking capacity at 400 V AC, built for 3-pole, 690 V AC drawout switchboards. It carries the Ekip Dip LI electronic release and replaces or stocks the moving element of an already-installed E6.2V cradle.

Selection Notes

This WMP is the moving part for the 5000 A, 150 kA E6.2V frame. The Ekip Dip LI release limits it to L (overload, long-time), I (instantaneous) — there is no adjustable short-time delay to hold through a downstream fault. That suits a feeder position where fast, instantaneous clearing is preferred over coordination with a smaller breaker below it; for an incomer or bus-tie needing that coordination, the Ekip Dip LSI sibling at the same 5000 A rating adds the S function. Its V-class short-circuit performance level raises Icu to 150 kA between 400 and 440 V AC, tapering to 130 kA at 500-525 V and 100 kA at 690 V — specify it over the H-class sibling's flat 100 kA only when the calculated prospective fault current calls for that extra margin.
