I am not sure about your agency review, but I have always used the Telcom rated fuses from Raychem (TR600-150)and there has never been a problem. This is based on UL 60950 anex B testing via the flow chart on page 200 and 201. I believe that refers to compliant PSTN fuse protection devices. Please keep in mind that the EU and UL versions of 60950 are slightly different.

Hi Colleagues,
I intend to use an overcurrent protection device, the Raychem polyswitch
TS250-130, on an analogue modem interface for Europe and the US. I know this
should be OK for Europe but is the 250V rating (ITU lightning protection to
1.5KV) OK for the US?
Kind Regards
Alex McNeil
