Circuit breaker Supervision.

I am after something that can alarm if a circuit breaker trips.

What I am thinking is a 1 unit wide din module that sends a light beam across the switch board to another 1 unit wide din module at the other end of the switch board. if any of the breakers trip this will break the light beam and send of an alarm.

There are devices that monitor individual circuits but I want to monitor all 8 in 1 go. I don?t need to know which one tripped just that 1 has tripped.

Clipsal used to make something like this for the surge arrestor it send a beam of light through a hole and if any of the surge arrestors tripped it blocked the beam.

Any ideas anyone ?

Page 35. Is that what you are looking for?

Can be found on page 197 of the current Trade Pricing Guide

 

I use these on some of my RCD/MCB's now. They will do what you want as they offer a contact closure. They just fit up against the clipsal breaker and the pin slides into the little "switch" on the front to couple to it.

They will add 1/2m width to your breaker though.

Its not what you asked about though. You could daisychain them all togther to geta trip indication for any, but you are still monitoring every MCB individually.

Be carefull with clipsal product being replaced with Schneider

I am posting this so other don?t make the same mistakes.

I have been using 4A2C10 Aux Contacts with 4RCBE116/30 circuit breaker.


All works well.

I ordered some more for another job and found the 4RCBE116/30 has been replaced with a Schneider equiv. Clipsal keeping the same part number.

Problem 1 they are totally different size and will not fit in the same switch board.

Problem 2 Schneider feed from the top the Clipsal feed from the bottom.

Problem 3 the 4A2C10 no longer work with it.

I wish Clipsal would use a new part number......

I have been bitten by this Schneider assimilation before but not this bad.

Busbars don?t fit.

The Schneider surge module has holes that bus bar did not fit any more.

I buy clipsal because there was a lot of engineering and thought in the design and everything just fits.

These days nothing fits. I am losing my loyalty to the clipsal brand.

I have noticed distributors no longer promoting Clipsal for the same reasons and promoting Legrand product.

CIS seem to go to a lot of trouble to make sure things are compatible and backwards compatible. Please don?t give up this ideal like the rest of the company.

Are other finding the Schneider substitution/rebrand to Clipsal parts very frustrating?

A2c10

It seem clipsal have discontinued the 4A2C10 and have no replacement.

Any one know other way to monitor CB status ?

Old thread but a couple of thoughts...

Heinlec make a exit & emergency monitoring relay that can monitor multiple circuits (either 3 (HLR3) or 12 (HLR12) circuits).

The operation (from memory) is the device looks for voltage on all channels if one or more channels has no voltage the device has a contact that changes state.

Another possibly cheaper option would be a phase failure relay (Elko (ipd group), eaton, abb (and I'm sure SE) all have devices in their catalogues.

Another possibly even cheaper option would be to have a 240v relay powered from each circuit then series up all the relay contacts. If a terminal style relay was used the space required would be minimal Weidmuller do one 6mm wide.

Just some thoughts that might be of use to someone.

 

Good options Thanks
