![]() ![]() ![]() The second one has more common German sockets, which are used in more places, with varying voltages, which could be why they mention the whole range on the datasheet That's why it's a surge protector, not an overvoltage protector.īecause of this, the nominal voltage doesn't matter all that much whether it's made for 220V, 230V or 240V, you're always going to end up somewhere around 500V when it trips (and spoiler alert, probably exactly the same voltage on all versions, because they don't bother redesigning a 220V surge protector for a 230V system or vice versa, 10V is no important difference when you're trying to stop 1000+V surges)ġ I suspect the first one says "230V" because it's very specifically intended for the French market (as you can see from the sockets it uses) and in France they all use 230V, so there's no reason to mention any other number on the datasheet. ![]() (even though 260V is technically too high). It's not like 260V would trip the surge protector, it's just not enough. Say you had a 240V protector, it'd probably start kicking in for surges at around 500V. 1 In general though:Ī surge protector usually begins to act on surges around 2x the normal operation voltage. You'd have to ask the intern who created the datasheet. Why aren't they just listing everything as 220-230-240V compatible?
