What you're actually specifying
The ABB 1SDA071073R1 is a Sace Emax.2S 2500, 3-pole AC circuit breaker carrying 267 W power loss at rated current.
Read the endurance curve, not the headline amps
Electrical durability is 8000 cycles at Ue ≤ 440 V and 700 cycles at Ue = 500...690 V, at 30 cycles per hour. Mechanical durability is 20000 cycles at 60 cycles per hour.
Sourcing posture
Lead time on this code runs 4–6 weeks quoted to order, which is the normal ABB Emax 2 channel cadence rather than a distressed-supply signal. If the.2S endurance profile above 500 V is the binding constraint on your single-line diagram, the -frame sibling is the documented same-class alternative worth weighing before the BOM freezes.
