Title: Volex MCB Replacement?
Post by jazzyman on Aug 17^th, 2016, 11:38am

I am trying to find a replacement Volex 16amp MCB VB16, looks like they are unavailable anywhere. Is there another brand that can be used for a direct replacement?

Wylex and some Crabtree. All made by Electrium and identical.

These Volex ones were recalled, some dodgy batches. Worth checking any B6, 10, 16 ones you have.

Since then, they have redesigned them slightly, but they still fit.

Thank you for the information. I am replacing the three MCB's= 2xB6 and the 1xB16. I do suspect that they maybe from the recalled defective batch, house was rewired around 2009 and the one bad MCB has gone open circuit.

There is a bit of confusion if the Wylex and the Volex are interchangeable? Apparently there is a difference with the busbar location, see pic

I managed to pick up volex replacements from ebay. As suspected the faulty mcb was from the recalled batch, also changed another two which were also on the list of recalled mcb's..

Recall means you should be able to get replacements foc.

Yes, Electrium would of sent someone out, or paid a spark to check them for you.
