Merlin Gerin Masterpact M16N1 - 1600A Circuit Breaker Test
HTML-код
- Опубликовано: 8 сен 2024
- This is a Merlin Gerin Masterpact M16N1 Circuit Breaker rated at 1600A/690VAC (Roughly 1.9MW 3-phase energy!) I do a short inspection of the different parts of the breaker and make attempts to operate it outside of its normal environment. For all schematics, pictures and how I got it to work, can be found described in details in the discussion thread: highvoltagefor...
The Masterpact M series circuit breaker is used to protect and control low voltage distribution systems. It can be installed in main LV switchboards (incoming units, main and secondary outgoers).
Nominal current: 800 to 6300A AC
Breaking capacity from 40 to 150 kA rms
Voltage rating: up to 690 V
Versions: 3 and 4-pole. Fixed or drawout.

It's actually 10mm X 80mm = 800mm2. Crazy

I've worked for this company, many years ago, as field engineer for UPS systems. My colleague did the service and repair for this circuit breakers. Now I see first time whats inside. I remember only for this brassy sound I heard often, when he tested these breakers in the room next door.
I love getting these feedbacks from old users or maintenance technicians that once worked with the stuff I find and do teardown on :)
Cool video buddy! Many thanks from Melbourne Australia
Thank you. Do I spot yourself and a daughter in your profile picture playing with some electronics together? :)
I work at a power plant and almost all of our breakers are that size or larger. On the low voltage side our largest are ITE/Gould K3000 (480V x 3000A). On the medium voltage side we've got some ITE/Gould 15HK1200's (13800V x 1200A) which are just huge.
Unfortunately also getting too big to make it unto my work bench :)
That is awesome. Amazing stuff with some serious engineering.
Cant believe you put that thing on your bike, amazing
Kid seats are for parts, the kids can walk next to the bicycle :)
That's a baby breaker, but a really cool find. Take note, in working with breakers this size and much, much larger, normally the closing spring charges the trip spring when you close it. So be careful if you find yourself in a situation with the breaker closed and the semaphore shows discharged, the trip spring may still be charged. Not 100% sure on MG breaker semaphore if it will still show charged with trip spring charged and closing spring discharged.
Also, the rusted part you mention with the arcing on it. That is part of the arc chute, when the breaker trips the arc will climb up that conductor up in to the arc chute to be extinguished. As sucj it will normally show signs of arcing.
Also, also, normally these operate around a 5 cycle trip or 5 cycle close time frame. Some times faster and some times the breaker will be faster to close than trip. But normally tripping is the faster operation. Just to give you an idea of the times you should be seeing with the high-speed cam. Larger substation breakers are 3 cycle trip or some 500kV breakers are even down to 2 cycle trips!! Higher the voltage, the higher amount of power that can develop in a fault condition and needs to be cleared even faster.
You can look up GE Power Break or Cuttler-Hammer Pow-R breaker manuals for reference to this breaker if hard to find manuals on it. I have a few manuals if you are interested.
I am not taking home a larger breaker on a bicycle ;) Trip spring must be much smaller and hidden somewhere inside? I got some closing and opening times recorded from the high speed that will come in next video. I love getting these feedbacks from old users or maintenance technicians that once worked with the stuff I find and do teardown on :)
@@KaizerPowerElectronicsDk Hahahaha, that was big enough for a bicycle! Been a few years since I worked on the smaller breakers like that, but on the larger breakers as a rule of thumb the closing spring charges the trip spring(s). So the closing spring will be much larger since it has to close and charge a trip spring. This breaker may use the same spring, but normally the close and trip are separate mechanisms. You can always watch the big spring and see if it releases a but when you trip it. Rather mention it and it not apply to this specific breaker than not say something and see a video with 9.5 fingers.
It must be a secondary trip spring, as the main large spring that is visible do not move at trip. Thank you for sharing your knowledge for safety!
@@KaizerPowerElectronicsDk No problem, glad I was able to help out a bit.
Reminds me of jurassic park a bit...i love it
It was some tense moments :)
I remeber that seen as well.
We have four 1200 Amp the main building breaker is 3000 Amp, all 3 phase 480 VAC 60 Hz. We had probls with the GFCI tripping on one of the 1200s so we have an electrical maintenance company come in every few years and calibrate and certify the breakers.
We lost part of a week when a ground fault tripped the main breaker, which failed and shut down our whole other campus. The breaker was no longer manufactured and had to be shipped from god only knows where.
Shows the value of preventive maintenance AND upgrading when a product goes into classic mode. Companies that build these systems usually gives a 10 year warning on spare parts going out of the catalogue.
Gosh, I really want to see the spark arrestor chamber in action and the contacts going BANG¡... And it will be more cool in slow motion
Pd: Love the vid and the click sounds of massive industrial contactorss btw those springs are mean
Slow motion is in the works
very cool, reminds me of jurassic park, push to close scene :D
Ha that's cool would like to try it on my big caps🤣 nice vid mate👍👍
Didn't you also have a breaker about this size in its original enclosure with feed horns and everything?
@@KaizerPowerElectronicsDk similar mate but not quite as big as that monster 😂😂👍👍
Nice, it seems so unreal ... and oversized.
I know the struggle of the bike, I olways find the best (and biggest) stuff when I'm on my bicycle. ;)
This takes the price for heaviest thing on a bicycle, but many years ago I dragged home a 120kg isolation transformer on a trolley, also 2 km :)
Why didn't you order a taxi. pulling a 120KG transformer 2KM is crazy. How the hell did you even lift that on the trolley, let alone pull it.
I hope you didn't need to go up any hills.
awesome
How do I electric charge the breaker
1.1MW, serious stuff! Where was it used?
1600A at 690V 3-phased is nearer 1.9MW! I only mentioned single phase in the video :) I am not sure exactly where it came from, but 1600A feeder into a large industrial complex is not uncommon.
@@KaizerPowerElectronicsDk I was counting at 3x 400V 🙂
Hi, I have (10x) 1600A , merlin gerin breakers interested in buying from me?
Now discharge few thousands Joule capacitor bank though it. :P
Soon...
Like the destruct-o-tron that Mike Harrison (mikeselectricstuff) built. I think this would survive that.
After a few tries, I think that anything above 10 kJ will do some serious damage to the contact points. But that is also a reverse load of what it is designed for, I doubt this was built to switch in a high voltage circuit :)
ooh ! Beefy :D

Send the manual please
Ask Schneider. I am not a manual library.
You need ocb I have a acb
