Is 40A continuous rating on relays? I was shooting for 50A resistive / AC-1 so that there is no possibility of objection when it gets inspected.
I was looking at these enclosed IEC ones (not all 50A, because it turns out there's a supply chain shortage). I want something that has the same physical protection rating as one of those European home electrical panels.

(Ignore the coil rating, I was planning on picking one based on convenience to wire up & availability/simplicity of surge suppression)
Also found these, but they smell of sketchy Chinesium:
