UL 1449 too, I'm guessing at least type 2 because of its far greater impulse handling characteristics if not type 1+2.
I was going to get a type 2 SPD Siemens Boltshield 140kA (FSPD140) for residential 120/240 VAC use until I saw the specs on the emp shield. The FSDP140 is actually a relabeled Raycap device with barely anything in it but 2 combined hybrid MOV-like 3 terminal devices. The previous gen FS140 is actually a pile MOVs.
