On a linked matter...

We had notification today about counterfeit MCBs coming onto the UK market. Believed to originate in China - surprise.

When opened up all that was inside was a straight switch, no trip mechanism at all.

So take care folks.

Received the official Alert documents today about the dodgy MCBs; unfortunately the copy is not good enough to repeat here.

They are made to imitate Merlin Gerin, the picture shows ..
1 x Merlin Gerin Multi 9 K60N B6 MCB
1 x Multi 9 C45N C10 MCB

When these units were drilled open they were found to NOT contain an overload element or any short circuit capability, they are simply a switch

So all I would suggest is that you take extra care when at your local wholesaler, he may not know what he has been sent.

edit: If I did what I ask others to do then this would have been included first time.....

Checking with Google brought up these pictures..
