OkiePC (Customer) asked a question.
The part number for that SPD is 908 090 and should be listed on the back side of the unit as shown.
908 012 is the part number for the replaceable protection module to be used with the device.
I'm not exactly sure what you mean by "it would not pass 120V". It should pass voltage (straight to ground) only when voltage spikes or the unit has tripped.
Okay, that is exactly how mine looks. The 230V max continuous voltage rating threw me.
EDIT: Now that I am looking at the data sheet in the office lighting, I see that I had it wired wrong. I am a d****t at least once a week and this one is surprisingly d****y, even for me.
