Frequently asked questions
Will 1SDA054456R1 drop into a panel that was specified around 1SVR427071R0000 without rewiring?
Not on the evidence here. 1SDA054456R1 weighs 2.08 kgs versus the 1SVR427071R0000 at 0.86 kgs — more than double — so the two are not in the same handling class and the panel support, mounting, and wiring layout need rechecking rather than assumed compatibility.
