Unknown devices help needed: Circuit Breakers

[korolev]

Hello there, I have some electronic devices which I need advice/suggestion on where I might be able to find people who are interested.

My dad's friend had them for his workshop machinaries if I haven't mistaken and is planning on retiring... hence these devices.

There's a bunch of circuit breaker ranging from 15Amps to 250Amps (brand new & used) and they're all "3 poles".

I am not familiar with these devices and hardly know their exact use.

The brands are Fuji, Mitusbihi, Terasaki and Merlin Gerin.

Do you guys have any idea on the actual use and perhaps where/what kinda stores I might be able to find interested parties?

Incase you're wondering, here's some images:

Thank you guys.

the circuit breakers you called are MCCBs an electrical panel builder would be intressted (when the price is right) the new ones are easy to sell but the(ab)used ones not, keep them for hobby or sell them for somebody with a hobby

you could also aproach technical departments from factorys as these devices do burn out (and more often as people think)

the merlin gerin in the picture i would donate to the museum

brands are considered as A and semi A brands (better than the china ones)

sucsess with the sale

rjvh, thank you so much! you really know your stuff man! =)

The last device looks like a pressure to voltage (well current) conversion.

At a guess you'd put 0-1 bar pressure in and get an analogue current of 4-20ma out

Close but not quite!
It is a pressure transmitter, 4 to 20mA output, but the input is 0 to 1 milli-bar.
Which is a rather low pressure!

thanks guys! from my assumption, these stuff aren't worth much right? i've got 6 of them pressure transmitter!
