surge, lightning arresters vs. surge suppressors

(OP)
Hi...

Can someone provide a technical distinction between a surge arrester and a surge suppressor?  I believe they are both given under the umbrella term, "surge protective device"?

 thx,

RE: surge, lightning arresters vs. surge suppressors

To me, the diff is:

1.  A surge arrestor is used for MV/HV applications.
2.  A surge suppressor is something that you use in your home to protect your electronic appliances.

RE: surge, lightning arresters vs. surge suppressors

Surge arresters = lightning arresters
surge suppressors = TVSS = transient voltage surge supressors

IEEE abandoned the term "lightning" arrester many years ago, but old habits die hard, especially when it involves the NEC.  

I agree with Mike that surge arrester generally refers to medium and high voltage.  

I believe that UL refers to SPD - surge protective devices, which I would equate with surge supressors.
