<DIV><BR></DIV>
<DIV>The Citel products which mount to a DIN rail have an LED indicator which goes dark once the surge elements have been sacrificed. Also some of their units have an auxiliary switch which can remotely indicate a blown condition. This is in the form of dry contacts..a normally open and a normally closed one, so various indicator circuits can be designed around that. The contacts have a low amp AC rating and also a (lower amp) DC rating but I do not remember the numbers at present. </DIV>

<DIV>If its really lightning country, and a really expensive off grid system, I use Polyphasor, but they have their own issues. (very expensive, no UL listing, loose internal connections, nuisance tripping, need a large J-box to mount them inside, etc.)</DIV>
<DIV>I haven't tried the Citel stuff, but it looks to be listed, and mounts on a DIN rail. After installing a couple hundred Deltas, I'd try something else at this point.</DIV>

<DIV>I guess my thought is a little off topic, but are lightning arrestors even worth using at all? My logic has always been that if lightning does indeed strike that it's likely going to blow the arrestor and and inverter. We don't have much of a lightning issue issue in the Bay Area so I don't have any direct experience.</DIV>
