NVR switch, (NO VOLT RELEASE) 240 volt, single phase .

Cant find any nvr's at a suitable price with built in light or without
light, come to that.

Cant find any small lights to fit into nvr that are not switches

can you guys ascertain weather these little lights will be suitable ..

I intend to leave them in the switched on mode ..and in the casing of
the nvr connected to the output side .

This will prevent me leaving the nvr powered up ...when the machine is
accidentally switched off on the reversing switch

Have a look

He has different colours ...but i reckon the blue looks best

That is the switch rating!
Your recent posts on electrics do cast some doubt other whether you 
should be doing this sort of work yourself.

Put it this way bob

if i had to pay someone to do any electrical work

i would not be able to have installed any of my machines

therefor

i would not be into any sort of machining at all .

i would not be asking silly questions ..

because i simply cant afford to pay someone .

BTW .Ive had several electricians look over my past work

who commented they could not have done a better job themselves

just because i don't understand text book abbreviations for things

does not mean I'm not very safety conscious

the very fact that I'm asking questions on here means i am .

so i look to you guys to fill in the small blanks in my knowledge

after all thats what t he forum is all about ...
helping people ....i hope

all the best.markj

ho ho ho

have a jolly good laugh

I've worked around and by the side of electronics engineers,
electricians all my life

oh yeah, very knowledgeable they were as well

all graduated with honours ..degrees   and big smiles.

they had one thing in common.

..They all made mistakes ..
They all got shocks
They all blew things up and burnt things out

and i bet you have as well .!!!

so far I've been lucky ...I'm careful

and i bet you you've said that to yourself many a time ..

now, how about helping me out a bit...please

Markj

If you're planning to use this switch in stead of the NVR then 3A
should just about be enough, though I'd prefer some more headroom for
a 550W motor. I assume the LED is internally powered within the
switch.

If you're planning to replace the switch in a NVR with this then it
probably won't do as it's a latching switch and the On switch for a
NVR needs to be momentary.

If you're planning to use this purely as an indicator then it's an
expensive way to buy a light, but could do the job.

By NVR do you mean contactor?
If so why not wire a light across an outgoing phase and the neutral?

That was my plan,, the light would be more like a neon on a normal
switch

Was not planning to run the machine through the light switch, at all

Just to put it on the output like you said mark .

Go to RS componebts (http://uk.rs-online.com/web/) and search on "no

The switch may be rated at 240v but I would think that the LED is
meant to be supplied with low volyahe DC.  That has more often been
the case in my experience.  All you need is a small 240v lamp and you
could mount that on the outside of the NVR case in an extra "box" is
required.

Mark,

I did not mean to cause any offence.
My concern was based on the motor reversing thread when you said you had 
problems reading switching diagrams.
Yes this is the place where we seek and get help.
I'm sorry if I upset you.

I did go to the RS site yesterday

but the picture shown is generic ..and I'm unsure what I'm buying

just phoned maplins up in llandudno...and the guy there has no idea
what a no volt release switch is and cant find one in his catalogue .

i don't have the catalogue either

so it looks like I'm going to have to make my way to llandudno ...and
see what they have ..

i need quality crimp on connectors as well ...will see if maplins
stuff is up to the job.

Trouble is the terminology.an NVR is a latched contact that opens when
the holding voltage is removed and has to be manually reset.
What I think you want is a contactor and overload to protect your
motor.If you ask for that people will know what you mean.
This lot here used to be very competitive on contactors.

Yes machine start/stop contactors are (usually) wired as NVR switches,
but some el cheapo machines are fitted with an NVR switch which
doesn't incorporate a contactor. I'm thinking of stuff aimed at the
DIY/small contractor market such as the little H-V bandsaws, some wood
planers etc.
There is I think some sort of legal requirement which these switches
are aimed to satisfy in the cheapest way possible.

Thats why the RS site has links to the manufacturer's data sheets, and
the components are identified by the manufacturer's part number.

I had emailed the guy with this a couple of times asking weather it
was  NVR

http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=140180247435

no replies

Anyway ...Ive bought it

Maplin's web site is in effect an online catalogue.
Not that I could find anything remotely ressembling an NVR switch

An interesting example of the way Google is abused is that one of the 
results of "NVR switch" is a link to Maplin's site for a fantastic offer!
Still no NVR though.

Well, I hope you have a use for a motor switch with built-in thermal
overload protection (and no, it doesn't have NVR) because that's what
you have bought.

Doesn't have a built in light either.

You can see the maker and model number in the second pic on the
listing - its a Ziehl-Abegg S-ET 10E. A couple of minutes of work on
Google, as I just did (indeed, considerably shorter than it took me to
write this) would have taken you to the manufacturer's website here:

http://ziehl-abegg.com/ww/fans-product-group-6.html?dtl=1

and the right products page here:

http://www.ziehl-abegg.com/ww/fans-product-group-6.html?dtl=1

and finally the PDF of the instructions for it here:

http://www.ziehl-abegg.com/ww/download-526.html

Whatever solution you finally end up with, its now cost you an extra
£9.50. I guess you could sell it again on Ebay...

Seems very odd to me that you would be reluctant to buy from RS, on a
site where you know they sell NVR devices and they do actually provide
you with all the spec information you need to select the right item if
you only take the trouble to look at it, and instead seem perfectly
prepared to spend a similar amount of money on an Ebay item where you
have absolutely no idea whether it is what you want, and the seller
has, by your own experience, been considerably less than helpful in
providing any information.

I've taken many risks on ebay . the only way to get bargains these
days ...if someone described something right ..it goes for too much
money  :(..this is my first ...one thats ended up no good then..luck
of the draw.

Mark -

I've already given you all the pointers you need to figure it out. If
you can't figure it out from the information available to you, then
you are simply proving Bob M right...that there is some doubt (I would
say serious doubt) as to whether you should be doing this yourself.

Which just proves for the second time today what a lousy guesser you
are.

Hum-mm

TONY
Do you display this attitude to people who phone you up with problems
they are having with your Division Master

EG ...look you've got your division master ..Ive got your money ...and
it's not my problem anymore ....figer it out yourself !!

That RS web site, I get as far as here

http://uk.rs-online.com/web/search/searchBrowseAction.html?method=retrieveTfg&binCount=7&Ne=4294957561&Ntt=no+volt+release&Ntk=I18NAll&Nr=AND%28avl%3auk%2csearchDiscon_uk%3aN%29&Ntx=mode%2bmatchallpartial&N=4294957307&Nty=1


And no matter how far I delve ...I cant find a nvr in an enclosure for
under twenty ..then you got vat and postage

The above link shows products ...with data sheets about a number of
products on the same data-sheet

Among  the results "somewhere" are the cheaper ones ...that you have
to get an enclosure for ...or build one yourself

The data sheets ...talk about every product ...it's impossible to
ascertain ..which one they are going on about ...there is a rough
description ...which still leaves me without .

Guess, I will have to phone them up tomorrow.

Actually, a number of NVRs from well known makers don't have a
solenoid operated electro-mechanical contactor, but are able to be
mechanically latched when mains is present and the ON button is
pressed.  No mains releases the mechanical latch as does the overload
(overcurrent detection) mechanism and the OFF button.

The problem for anyone not familiar with motor control circuitry is
that one can find the same type of devices listed on different
stockist's catalogues and by different manufacturers as :-

Direct On-line Starters
Motor Control Switches / Starters
No-volt release switches (NVR)
Mains contactors
Motor Switches
Motor Starters
etc, etc.
with or without overload / overcurrent protection.

No doubt, someone will tell us that the correct name is none of the
above - in the same way as a "light-bulb" is really a "luminaire".

I know what I want so I can look it up in the catelogues.  In fact, I
sorted out the wiring on a mechancal "Motor Starter" for a fellow MEng
and bought an electro-mechanical type on e-bay which had over-current
protection that I removed, to make it into a simple contactor for use
with a 1-phase to 3-phase inverter.  Not so easy if you're not familar
with them.
