Chint MCBs

What do others think of these MCBs? Are they real? I'm seeing them on Amazon at questionably low prices.

The fact they might be substandard.

I think screwfix supply them too.

Just another example of why the electrical installation and maintenance trade, at ground level, is going down the pan.
The game is flooded with sub standard goods, of all types. Loads of cheap shyte.

Honestly, when I see them I think of this exact breaker.

Ah yes the untrippable circuit breaker , seen a few of these devices on YouTube and even on watch dog. They all are made exactly the same way with a piece of wire or bunch of twisted wires acting as the switch contact.
when you are paying £1.50 for an mcb what do honestly expect

I had pondered once on how hard would be to build a circuit with a big ~1R resistor and chunky triac that could sink around 230A for a single 20ms cycle of the mains to test MCBs magnetic trips.

But then I realised it would cost me more in time & money than just replacing any suspect MCBs for all the time I ever do it!

Wholesalers sell it here....

Functional testing of MCB's??

It might sound a bit daft but is there any way of functionally testing MCB's? It's easy to confirm whether an RCD is functioning correctly but is there any way of testing an MCB? I've just been reading about counterfeit goods and how some MCB's are manufactured with absolutely no working parts...

We use loads of there gear and very little issues
