By simply wiring the input/output of the fuses “in reverse”, you’d be able to save something like twice 20 cm in length, without reducing safety device function. Which for a total max of 60 seems huge. Would that not be allowed in whichever country this is? (You could also mount them upside down, given that din rail is symmetric, if you think input and output clamps are somehow holy.) The way it is here I’m not convinced the total length is in fact less than 60 cm.
Indian likely... the old UK phase colours were red/yellow/blue, or originally red/white/blue with a black N The UK's since harmonized to brown/blk/grey phases and blue N, but many countries still use our old colours. Personally I always still think of black as N... which could be dangerous these days :(
Thanks for the video, I have a few suggestions. Use an appropriate current-rated MCB instead of fuse (I believe you're using the maximum manufacturer allowed fuse rating here at 125 A). Also in your comment to Frederico Cunanan you mention how an SPD might create a fault as it ages. I think while it may have been prudent advice in the past, type 2 SPDs based on MOVs nowadays have an end of life indicator _and_ an internal disconnector to prevent diverting surge through a failed module/MOV. And if for some reason, the internal disconnector did fail and the SPD creates a fault in the circuit, simply remove the failed or faulty SPD module. Most SPDs today are modular like the Dehn SPD you use here. Dehn is a solid choice btw, +1 for that, bit expensive in India but we have really good standards compliant alternatives like Havells at a third of the price.
thank you for this video, i want help ,I want to connect advices called LDI (LARGE DECODER INTERFACE) which input voltage 240VAC+-10%,50HZ and the output 24VAC@3.15A,50 HZ.how do I connect voltage surge protector to this advice?
simple formula if your device watt is 1000 and you power supply voltage is 220 V your ampere is watt/volt that means 1000/220 =4.5(ampere).. so you can add fuse 10 ampere
Can it be installed without fuse? Am I correct in saying that, since you are installing fuses means you are protecting the Surge arrestors from getting damage due to over current? Once fuses broke will this not back fire to the Circuit breakers?
Hi Frederico Thank you very much for your contact and interest. The purpose of the backup fuse is to remove the surge arrestor from the circuit when it reaches the end of life. All MOV based surge arrestors begin their life as a high impedance connection to earth except during high voltage spikes at which point they switch to a low impedance connection to earth. As the surge arrestor performs its job over time it becomes more stressed and becomes a low impedance connection to earth. This is a permanent change, therefore to stop the surge arrestor from creating a fault condition the fuses will eliminate it from the circuit.
I thought the purpose of the fuses was to isolate surge protector in case there is a surge and surge protector grounds the mains but for some reason the breaker does not trip which could lead to burning of wiring. I recently started to look into installing one for home therefore looking at its working etc. Can you please guide me which type of surge protector to use in case the phases short with neutral (happened last week with a friend during rain which blew a lot of electronics). Also I thought they would last life time until they face surges, isn't that the case? How long will it last in years ?
125A HRC Fuse for backup prorction only for surge arrestors? I understand if 125A fuse installed on main feed for protecting the entire panel, but installing 125A fuse backup only for surge arrestors isn't it way way to big for the purpose? I mean isn't enogh using 6A HRC fuse for backup prorction of surge arrestors?
You do not have to use any fuse (s2=not to use) when main installation breaker is lower or equal 125A. it is intended to protect installation, than should be installed with good direct ground connection. All of those main breakers will melt and fuse together during lightening strike (most of them are no more than 10kA). Sure protector is your only hope, not to have most of equipment burned in your home.
Hello , can you please send me the schematics on how to connect this Siemens - TPS3A1220VX02-1 Phase Surge Protection Device, 120/240VAC. please I am lost
I have to thank you so very much for the fantastic presentation.
It is so easy to understand. Well done and keep it up

In UK 50cm is recommended max. The shorter the better....
It is easy to understand the way you presented it...
Could you provide the link from where you got the Electrical Crimps? Thanks
Thank You very much and 100% clear
Fuse in heigh voltage or heigh current will be cut the continuity the current
So what the benefit it
Thank you for excellent presentation. It was very helpful.
God bless you I sow agood presentation
What kind of electrical code is that, with Blue = Phase and Black for permanent neutral?
Indian likely... the old UK phase colours were red/yellow/blue, or originally red/white/blue with a black N
The UK's since harmonized to brown/blk/grey phases and blue N, but many countries still use our old colours.

Not silly american
I thought the cable is also connect to earth rod.

Why rotate you the Surge-Arrestor about 90 Degrees? Then you have shorter wires to them.

Why the fuse there is a MCCB pls explain
Why are you recording upside down?
how to calculate Fuse size [ampere] for surge protector?
simple formula if your device watt is 1000 and you power supply voltage is 220 V your ampere is watt/volt that means 1000/220 =4.5(ampere).. so you can add fuse 10 ampere
What
Sankalan Chakraborty said, but also check the manufacturer recommendation (from their datasheet) for maximum fuse (MCB) rating.
@@sankalanchakraborty2176 the HRC fuse is not carrying the load current but rather the surge current to ground through the SPD.
Can it be installed without fuse? Am I correct in saying that, since you are installing fuses means you are protecting the Surge arrestors from getting damage due to over current? Once fuses broke will this not back fire to the Circuit breakers?

Considering breaker is more pricey than Fuse ,so maybe Fuse should be on the front line considering it cost nothing to put new wire inside fuse

NO fuses!!. These are MCBs. No one uses fuses anymore.

6A not enogh! U must use 125A. this fuse use for backup LINE - not for backup prorction of surge arrestors!

Thank you good presentation
Great video tutorial ❤ thanks for sharing your knowledge and experience 🫡🇵🇭♥️
What is a surge arrestor
Hello , can you please send me the schematics on how to connect this Siemens - TPS3A1220VX02-1 Phase Surge Protection Device, 120/240VAC. please I am lost
Need those tools.
This is whole wrong. Wires are very long. Correct is bottom swich to bottom fuse holder and top fuse holder to top SPD.
Awesome video.
Great video
Typ of surge protecter dital plz
S2 kya hai
Good demo
شكرا
Yea
Nonsense where the supply main and load will be connected?
