In the current climate, where warnings about the dangers of couterfeit parts seem to pop up on verious sites, I unfortuatly find my self with a question on the subject.
Haveing some maximum Earth Fault Loop Impedance (EFLI) problems with some old QOE Square D MCB’s, that are know longer made.
Bought some of the newer type QOE’s, from an online store, as these have the type B,C,D range that the old one didn’t, they were all type 4, which would give a higher max EFLI, range and therefor compliance with the 17th edition.
However, some of them look suspect.
1/ The SCHNEIDER Logo is upside down on the suspect ones and the font of the CE mark is not the same
2/ The cut out by the busbar connection clip is much shorter on the suspect ones.
3/ The identification stamp has turned, and is not in line with the edge, as it is on all QOE's of this type we already have.
4/ Extra cut outs, these mirror the cut outs found only on the other side of all the QOE's we already have.
5/ Extra round recces not found on the QOE's we already have.
Also one of our production engineers says, there is a lot of shrinkage in the plastic moulding in comparison to the QOE's of this type we already have.
I have emailed the technical dept at Schneider, and recived this answer.
Thank you for the information, I have past it up to my managerand he will look into the mater.
So in the mean time I though I would ask here to see if any one else has come across this.
I can't seem to get a picture onto this that would help the above numbered discriptions.
Up Date
Schneider have asked to be send some of the MCB's to them for test to make sure, but think from the information and picture they are fake.
Actualy the say they will send two replacement if I send them the spec for the fake QOE MCB's, they must have a secrete supply!
