Hager SPD (SBP015N) showing red

PS - Fluorescent Fittings , 5 ft fittings cheaper than 4 ft fittings, even though more metal and glass they had larger volume of production runs!

Likewise - twin sockets cheaper each than single sockets sometimes

Calculators for sale - slight seconds/substandard £5 each or three for £4.

Ok I made that one up for a joke

Or examples where a "multipack" is cheaper per item than one, but the discrepancy between the selling price of one and the per-item price in the multi beggars belief.

(Delivery isn't "free", so it's not that...)

Hi

Three quick(?) questions-

As it seems that a failure indication seems to depend on the amount of red shown, attached are two photos one of the SPD in the house and the other in the garage. Is there enough red in the garage photo to say that they have failed?

The garage is fed from the house, but the garage breaker stays on for about 10 seconds then trips – even with the main switch off. Is it possible that the SPD has failed ‘shorted’?

This started yesterday, up to that point I had not thought about an SPD in the unit, never mind noting the colour

Given that they are replaceable units (according to the documents), they look easy to replace?

Happy New Year!

Hi

Yesterday we had a brief power cut for a few seconds. Apart from finding I was now the lucky owner of two dead computer monitors, on inspection of everything else I see that the Hager SPD's in my CU are showing red on the indicator panels. Hager say they are "end of life" - so does that mean just ONE power surge and these things need replacing? The SPD is only about 8 months old!

There's 2 modules and I presume SPB015n refers to the replaceable module not the complete kit? Seems though that the replaceable modules are about £100 each (I have two of them) whereas the kit which includes those modules is about £35. I saw the modules on ebay for about £16 but think I'll wisely avoid that as you don't know if someone has fiddled with them.

Should these things last more than one surge or was I really unlucky to have a major surge that wiped them out? The CU lid needs removing for replacement, but can this be done with the circuits still live?

Thanks
Dave

See response I got from Hager,
