13,500A surge suppressor. (Uh-huh?)

Any interest in taking apart a damaged led fixture that was contacted by a 15KV transmission line BigClive?

I’ve found that on mainland Europe they often tend to use , where we use . and vice-versa

This explains why these have a tendency to trip the RCD as they dump the surge to earth. My mother ran into this problem by plugging her treadmill into a protected power strip. The moment the treadmill motor started, the RCD tripped. With a regular power strip or the treadmill plugged directly into the wall socket, it operates fine. I also have a similar issue with my UPS (an old APC Smart UPS 1000). It will trip the RCD when I plug it in, but as long as I leave it plugged in when I reset the RCD, it works fine.

"Marketing wank" 👍🏻

Back in the mists of time I worked for an industrial instrumentation company that sold these for line protection. Some customers required a test certificate with all purchases. Now, if you fully test one of these it obviously destroys the discharge tube, so the method was to pick the next one in the production run and test it, and issue a certificate. I spent a happy week as an apprentice blowing these things up, all in the name of "testing"

I do have a tester that would do that, but it might fry the components in the process.

I have 2 of them at home to protect my electronics. Don't you have an High-Voltage tester to test the gas-discharge tube? P.s. the real expensive one which can test various voltage (at 1 or 2 mA?) I don't remember so good.

Was hoping it was designed for 13500 Amps. I guess it world probably stop that too by frying.

isnt using . for thousands normal in european languages...thought the dutch do that aswell...makes no sense :)

Or, some good Rammstein 😆

btw, "st" at the beginning of a word is pronounced "scht" in german (random youtube video: https://youtu.be/lyRURIDc1M8). Three standard stars for trying, though!

They also spell out exactly what the rating means on their site, and offers to repair/replace any connected device if the suppressor fails to match the spec, so if not else their insurance company has probably asked for some proof that the rating isn't just a random number. (edit: above written before I watched the end of the video where Clive explains where 13,500 number comes from. I guess that also explains the 4,500 rating on some other brennenstuhl products :-)

Brennenstuhl is a German company, their products can be found in most home improvement stores and they are in the mid-quality and mid-price segment. I wouldn't even be surprised if they actually put 13,500A pulses through some test devices during development (with all that 5 star quality program on their website).

Maybe countries that use the same square pin socket style?

It's the 20th, of June, 2013. https://www.iso.org/iso-8601-date-and-time-format.html

English, Arabic, and Farsi. Interesting!

On the bottom of the board it says HWM - 13.06.20. Does that mean it was made in 2013, expires in 2020, or is it somebody's birthday?

Thanks Clive.
