ABB 1SDA072651R1 E6.2V 6300 Ekip Dip LI 3p WMP 150kA Air Circuit Breaker

Rated 6300 A with a 150 kA breaking capacity at 400 V AC, the ABB 1SDA072651R1 is the E6.2V 6300 Ekip Dip LI 3p WMP withdrawable moving part of the SACE Emax 2 E6.2V frame. The Ekip Dip LI electronic release handles 3-pole protection up to 690 V AC, and the part is sized to rack into an existing E6.2V drawout cradle rather than a fixed enclosure.

Selection Notes

This 6300 A, 150 kA E6.2V unit is the drawout moving part that racks into the Emax 2 cradle. Its Ekip Dip LI release covers only L (overload, long-time), I (instantaneous), with no settable short-time delay. That makes it a faster-clearing choice for outgoing feeder positions where selective coordination with a smaller breaker is not required. Where the installation needs the breaker to ride through a downstream fault for selectivity, the Ekip Dip LSI sibling at the same 6300 A rating adds that S-function delay. The V performance level pushes Icu to 150 kA at 400-440 V AC (dropping to 130 kA at 500-525 V and 100 kA at 690 V), a step above the H-class sibling's flat 100 kA across the same voltage range — worth the difference only where the prospective fault current at this busbar actually exceeds 100 kA.
