Yes. One of the respondents, Ed Lethert, a respected Minneapolis-based consultant, 
recommended SurgeX products. I strongly second that recommendation. They make 
series-mode suppressors for branch circuits with ratings up to 20A and 240 volts. I 
have four of their suppressor units in my home (my office, my wife's office, ham 
shack, audio and video gear), and I specify them for virtually all of the pro audio 
systems I design.  They aren't cheap, but all SurgeX products are certified for Grade 
A (1,000 hits of 6KV), Class 1 (highest quality protection), Mode 1 (no contamination 
of ground) per UL1449 adjunct testing.  Most of their products also provide some 
EMI filtering. 

Quoting from the SurgeX website:  

"Caution: Do not confuse the endurance (adjunct) testing discussed in this document 
with the safety testing that UL are usually associated with. UL 1449 certification does 
not automatically mean that a product also passes the adjunct endurance testing 
(which is optional), it only means that the product has passed safety requirements."

I'm an independent consultant, and have no connection with any company, including 
SurgeX, and I do not work on any form of commission.
