ABB 1SDA071302R1 E6.2V 6300 Ekip Dip LSI 3p F HR 150kA Air Circuit Breaker

The ABB 1SDA071302R1 is a SACE Emax 2 E6.2V 6300 Ekip Dip LSI 3p F HR air circuit breaker, a fixed-mount 3-pole unit rated 6300 A with a 150 kA breaking capacity at 400 V AC. Rear horizontal terminals bolt directly to busbars, and the Ekip Dip LSI electronic release handles protection up to 690 V AC.

Selection Notes

In the fixed, rear-horizontal E6.2V frame, this 6300 A unit carries a 150 kA breaking capacity. Its Ekip Dip LSI release is the three-function version — L (overload, long-time), S (short-time delay), I (instantaneous) — so the breaker can hold a developing downstream fault open long enough for a smaller device to trip first. That selectivity makes it the right choice for an incomer or bus-tie, not a feeder end-point; where instantaneous clearing matters more than selectivity, the Ekip Dip LI sibling at the same 6300 A rating is the one to specify. 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.
